3. OPERATION
3.1 DC Voltage Measurement
1) Connect the black test lead to the "COM" socket and red test lead to the
"VΩmA" socket.
2) Set the selector switch to desired “V” position.
3) Measure the voltage by touch the test lead tips to the test circuit where the
value of voltage is needed.
4) Read the result from the LCD panel. The polarity of the red lead connection

5
will be indicated along with the DC voltage value.
Note:
a) If the voltage range is not known beforehand, set the selector switch to high
range and work down.
b) When “1” or “-1” is display, over-range is being indicated and the selector
switch must be set to a higher range.
c) Don’t apply more than 500V DC or AC rms to the input, indication is possible
at higher voltage but there is danger of damaging the internal circuit.
d) Use extreme caution to avoid contact with high tension circuits when
measuring high voltage.
3.2 AC Voltage Measurement
1) Connect the black test lead to the "COM" socket and red test lead to the
"VΩmA" socket.
2) Set the selector switch to desired “V” position.
3) Measure the voltage by touch the test lead tips to the test circuit where the
value of voltage is needed.
4) Read the result from the LCD panel.
Note: See DC voltage measurement note a)～d).
3.3 DC Current Measurement
1) Connect the black test lead to "COM" socket. For measurement up to 200mA,
connect the red test lead to the "VΩmA" socket; for measurement from
200mA to 10A, connect the red test lead to the "10A" socket.
2) Set the selector switch to desired “A” position.
3) Remove power from the circuit under test and open the normal circuit path
where the measurement is to be taken. Connect the meter in series with
the circuit.
4) Read the result from the LCD panel. The polarity of the red lead connection
will be indicated along with the DC current value.
Note:
a) If the current range is not known beforehand, set the selector switch to high
range and work down.
b) When “1” or “-1” is display, over-range is being indicated and the selector
switch must be set to a higher range.
c) The maximum input current is 500mA and 10A depending upon the jack
used. The F0.5A/500V fuse protect the current measuring circuits that
measure up to 200mA, the F10A/500V fuse protect the current measuring
circuits that measure from 200mA to 10A. The maximum time of the 10A
range measurement each is 15 seconds.
3.4 Resistance Measurement
1) Connect the black test lead to the "COM" socket and red test lead to the
"VΩmA" socket.

6
2) Set the selector switch to desired “Ω” position.
3) Connect tip of the test leads to the points where the value of the resistance
is needed.
4) Read the result from the LCD panel.
Note:
a) If the resistance value being measured exceeds the maximum value of the
range selected, an over-range indication will be displayed (“1”), select a
higher range. For resistance of approximately 1 megohm and above, the
meter may take a few seconds to stabilize, this is normal for high resistance
readings.
b) When the input is not connected, i.e. at open circuit, the sign “1” or “-1” will
be displayed for the over-range condition.
c) When checking in-circuit resistance, be sure the circuit under test has all
power removed and that all capacitors are fully discharged.
3.5 Diode Test
1) Connect the black test lead to the "COM" socket and red test lead to the
"VΩmA" socket.
2) Set the selector switch to desired “ ” position.
3) Connect the test leads across the diode under measurement, display shows
the approx. forward voltage of this diode.
Note:
Make sure the power is cut off and all capacitors need to be discharged under
this measurement.
3.6 Audible continuity Test
1) Connect the black test lead to the "COM" socket and red test lead to the
"VΩmA" socket.
2) Set the selector switch to desired “ ” position.
3) Connect the test leads to two point of circuit, if the resistance is lower than
approx. 50Ω, the buzzer sounds.
Note:
Make sure the power is cut off and all capacitors need to be discharged under
this measurement.
3.7 Data Hold
On any range, press the “HOLD” key to lock display value, press it again to
exit.
3.8 Back Light
On any range, press the “ ” key to light the back light, press it again to flash
the light.
4. Battery replacement
1) When the battery voltage drop below proper operation range, the “ ”

7
symbol will appear on the LCD display and the battery need to changed.
2) Before changing the battery, set the selector switch to “OFF” position to
power off and remove the test leads from the terminals.
3) Remove the two screws on the bottom case and lift the bottom case.
4) Replace the old battery with the same type battery.
5) Close the bottom case and fasten the screws.
Caution: Dispose the used batteries according to the rules, which are defined
Warning: If an explosion or fire hazard could occur through fitting a battery of
the wrong type.
5. Fuse replacement
1) This meter is provided with a F0.5A/500V fuse to protect the resistance,
Diode, Audible continuity test and the current measuring circuits which
measure up to 200mA, with a F10A/500V fuse to protect the 10A range.
2) Ensure the meter is not connected to any external circuit, set the selector
switch to “OFF” position to power off and remove the test leads from the
terminals.
3) Remove the two screws on the bottom case and lift the bottom case.
4) Replace the old fuse with the same type and rating:
5×20mm F0.5A/500V or 5×20mm F10A/500V fuse.
5) Close the bottom case and fasten the screws.
6. MAINTENANCE
1) Before open the bottom case, disconnect both test lead and never uses the
meter before the bottom case is closed.
2) To avoid contamination or static damage, do not touch the circuit board
without proper static protection.
3) If the meter is not going to be used for a long time, take out the battery and
do not store the meter in high temperature or high humidity environment.
4) Repairs or servicing not covered in this manual should only be performed by
qualified personal.
5) Periodically wipe the case with a dry cloth and detergent. Do not use
abrasives or solvents on the meter.
