• Measurement of electric resistance
1. Turn the rotary switch to the appropriate position.
2. Connect the test lead in black and test lead in redto COM input socket and V/Ωinput socket
respectively.
3. Use another two ends of the test lead to measure the electric resistance of the circuit to be measured.
4. Read the measured electric resistance value on LCD screen.
Notes:
* The measured value of the electric resistance of the circuit differs a bit from the rated value of the
electric resistance.
* To ensure measurement accuracy, in attempting a low resistance measurement, first put two pen-shaped
meters in short circuit and capture the resistance reading of these short circuits. Then subtract the
aforesaid reading from the measured resistance.
* At 60MΩposition, you have to wait a few seconds before the reading grow stable. This is quite normal
for a high resistance measurement.
* When the meter is in open circuit, the display unit will show "OL" that indicatesthe measured value
is over the measuring range.
3.2.3 Diode test

beeper will soundcontinuously. If the measuredresistance is between 40Ω and 60Ω, the sensor
LED (red indicator) will be on.
3.2.5 Capacitance measurement
To avoid the meter or the measured equipment from damage, do not attempt a capacitance
measurement unless the operator has already cut off all power sources for the circuit to be measured
and fully discharged all high-voltage capacitors. Use the DC voltage position to determine that all
capacitors have been discharged.
• The measuring ranges for the capacitance of this meter are 6.000nF, 60.00nF, 600.0nF, 6.000μF,
60.00μF and 600.0μF,6mF,100mF.

10.00A; and AC current measuring ranges: 60.00mA, 600.0mA, and 10.00A.
• Measurement of current:
1. Turn the rotary switch to the appropriate position.
2. Connect the test lead in black to COM input socket. Connect the test lead in red to a mA input
socket when the measured current is less than 600mA; connect the test lead in red to a 10A input
socket when the measured current is 600mA~10A.
3. Disconnection ofthe circuit to be measuredConnect the test lead in black to the endof disconnected
circuit (the voltage is lower) and connect the test lead in redto the endof the disconnected
circuit (voltage is higher).
4. Connect the power to the circuit and capture the displayed reading. If the display unit only shows
"OL", it means the input is over the selected measuring range. At this moment, turn the rotary switch
to a higher measuring range.
3.2.8 NCV test (non-contact voltage detection)
Turn the rotary switch to NCV position, and place the top of the meter approach the conductor. If
the meter detects the AC voltage, the indicators for signal density (high, medium and low) will be on
in accordance with the detected density, while the beeper will sounds alarms at different frequencies.
Note:
1. Voltage may still remain in the absence of any indication. The operator shall not rely on non-contact
voltage detector to check the presence of voltage. The detection operation may be affected by
various factors, including socket design, insulation thickness and type.
2. When the voltage is input into the meter's input terminal, the voltage sensor LED may be on as a
result of induced voltage.
3. External sourcesof interference (like flashlight and motor)may trigger non-contact voltage detection.
3.2.9 Live line test
