attempt to make any measurements. Instead refer to
sec.14 Return for Repairs.
Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is

Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V

instrument jacks. If any abnormal conditions exist do not
attempt to make any measurements. Instead refer to
sec.14 Return for Repairs.
Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is
within that next lower range.
5. When measurements are completed, disconnect the
test leads from the circuit under test. Remove the test
leads from the instrument.
Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V
battery test range. CAUTION
To avoid electric shock, instrument damage and/or
equipment damage, do not exceed 10Vdc while set to
take measurements in the battery test range.
3. Connect the test leads to the 1.5Vdc battery under
test. Normally a good 1.5Vdc battery will read above
80.0mA. Normally a good 9Vdc battery will read
above 22.0mA. Consult the battery manufacturer for
complete battery specifications to determine actual
battery life remaining and condition of battery.

"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is
within that next lower range.
5. When measurements are completed, disconnect the
test leads from the circuit under test. Remove the test
leads from the instrument.
Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V
battery test range. CAUTION
To avoid electric shock, instrument damage and/or
equipment damage, do not exceed 10Vdc while set to
take measurements in the battery test range.
3. Connect the test leads to the 1.5Vdc battery under
test. Normally a good 1.5Vdc battery will read above
80.0mA. Normally a good 9Vdc battery will read
above 22.0mA. Consult the battery manufacturer for
complete battery specifications to determine actual
battery life remaining and condition of battery.
Sec. 9 MAINTENANCE
Maintenance consists of periodic cleaning, battery
replacement, fuse replacement and recalibration.
Sec. 9.1 CLEANING
The exterior of the instrument can be cleaned with a soft
clean dry cloth to remove any oil, grease or grime from
the exterior of the instrument. Never use liquid solvents
or detergents. If the instrument gets wet for any reason,
dry the instrument using low pressure "clean" air at less

Before making any measurements always examine the
instrument and accessories used with the instrument for
damage, contamination (excessive dirt, grease, etc.) and
defects. Examine the test leads for cracked or frayed
insulation and make sure the lead plugs fit snugly into the
instrument jacks. If any abnormal conditions exist do not
attempt to make any measurements. Instead refer to
sec.14 Return for Repairs.
Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is
within that next lower range.
5. When measurements are completed, disconnect the
test leads from the circuit under test. Remove the test
leads from the instrument.
Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V
battery test range. CAUTION
To avoid electric shock, instrument damage and/or
equipment damage, do not exceed 10Vdc while set to
take measurements in the battery test range.
3. Connect the test leads to the 1.5Vdc battery under
test. Normally a good 1.5Vdc battery will read above
80.0mA. Normally a good 9Vdc battery will read
above 22.0mA. Consult the battery manufacturer for
complete battery specifications to determine actual
battery life remaining and condition of battery.

damage, contamination (excessive dirt, grease, etc.) and
defects. Examine the test leads for cracked or frayed
insulation and make sure the lead plugs fit snugly into the
instrument jacks. If any abnormal conditions exist do not
attempt to make any measurements. Instead refer to
sec.14 Return for Repairs.
Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is
within that next lower range.
5. When measurements are completed, disconnect the
test leads from the circuit under test. Remove the test
leads from the instrument.
Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V
battery test range. CAUTION
To avoid electric shock, instrument damage and/or
equipment damage, do not exceed 10Vdc while set to
take measurements in the battery test range.
3. Connect the test leads to the 1.5Vdc battery under
test. Normally a good 1.5Vdc battery will read above
80.0mA. Normally a good 9Vdc battery will read
above 22.0mA. Consult the battery manufacturer for
complete battery specifications to determine actual
battery life remaining and condition of battery.

Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is

Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.

attempt to make any measurements. Instead refer to
sec.14 Return for Repairs.
Sec. 8.1 VOLTAGE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"jacks.
2. Place the range selector switch into the
600DCV/600ACV position if a dc voltage is to be
measured or into the position if an ac voltage is to be
measured. Always start in the highest range of the
function to be measured.
CAUTION
Toavoid possible electric shock, instrument damage
and/or equipment damage, do not attempt to take any
voltage measurements if the voltage is above 600Vdc or
if the voltage is unknown. 600Vdc is the maximum
voltages that this instrument is designed to measure.
The "COM" terminal potential should not exceed 600V
measured to ground.
3. Apply the test leads to the two points at which the
voltage reading is to be taken. Be careful not to touch
any energized conductors with any parts of your body.
4. Turn the range selector switch to the next lower range
for a more accurate reading only if the reading is
within that next lower range.
5. When measurements are completed, disconnect the
test leads from the circuit under test. Remove the test
leads from the instrument.
Sec. 8.2 CURRENT MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "mA" terminals.
2.Place the function switch to the 200mA position.
Always start with the highest range of the function to be
measured. CAUTION
Donot attempt to take a current measurement if the
current is unknown or above 200mA. The "COM"
terminal potential should not exceed 500V measured to
ground.
3. Completely de-energize the circuit in which the current
is to be measured. Place the DMM in series with
the conductor carrying the current which is to be
measured. Energize the circuit.
CAUTION
Before changing ranges, always de-energize the circuit
completely.An open circuit exists between the test leads
during range change on the DMM.
CAUTION
The mA ranges are fuse protected. To avoid possible
electrical shock, instrument damage and/or equipment
damage do not:
1. Attempt to take mA current readings on circuits having
more than 200mA current flow.
2. Impress a voltage between the "COM" and "mA"
terminals exceeding 250Vac/dc. Some circuit damage
may result for voltages below 250Vac/dc.
3. Raise the "COM" terminal potential above 500V to
ground.
4. Energize the circuit. If the reading is within the next
lower range, switch to that range after completely de-
energizing the circuit under test. Continue changing to
lower ranges if the reading is within the next lowest
range to obtain the best accuracy.
5. Completely de-energize the circuit before removing the
test leads.
Sec. 8.3 RESISTANCE AND DIODE MEASUREMENTS
1. Insert the black and red test leads into the respective
"COM" and "V-Ω"terminals.
2. Place the range selector switch into the Ωrange
desired for a measurement. (The test range measures
resistance from 000 up to 1999 and is used to test the
forward resistance value of diodes.
The diode check entails injecting a given current into
the diode juction to be tested and reading the voltage
drop across the diode.
CAUTION
All resistance and diode measurements should be taken
onde-energized circuits only. To avoid possible electrical
shock, instrument damage and/or equipment damage do
not connect the "COM" and "V-Ω"terminals to circuits
having a potential difference exceeding 250Vdc/ac. Do
not connect the "COM" terminal to potentials exceeding
500V to ground.
3. Completely de-energize the circuit or device which is
to be measured. Connect the test leads to the device
(the red test lead is positive with respect to the black
test lead). When measuring a diode, connect the "V-
Ω"terminal to the anode. A reading of indicates an
overrange condition. This will occur with the test
leads open on all resistance ranges. If overrange
occurs
when taking a reading, switch to the next highest
range.
NOTE: On the diode test range, a [1] reading indicates a
resistance greater than 2K which normally means a
defective open circuit diode. Be certain the diode anode
is connected to the V-Ωterminal.
Sec. 8.4 BATTERY TEST MEASUREMENTS
1. Insert the black and red test leads into the respective
“COM” and “V” terminals for 1.5Vdc and 9Vdc.
2. Place the range selector switch into the 1.5V or 9V
battery test range. CAUTION
To avoid electric shock, instrument damage and/or
equipment damage, do not exceed 10Vdc while set to
take measurements in the battery test range.
3. Connect the test leads to the 1.5Vdc battery under
test. Normally a good 1.5Vdc battery will read above
80.0mA. Normally a good 9Vdc battery will read
above 22.0mA. Consult the battery manufacturer for
complete battery specifications to determine actual
battery life remaining and condition of battery.
