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

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.

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 “ ”

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.
