Ⅱ. Operating Instructions
When using the instrument for the first time or facing the energy
shortage of the batteries, please open the cover of the battery box and
put 6 5# batteries into it. Pay attention to the battery polarity.
When external adapter is supplying power, the internal battery power will
be cut off, and the battery cannot be charged at this time.
Attention: Please choose the power supply mode ( ).
Insulation Resistance Measurement
1. Turn the knob to the position of the corresponding function in
accordance with the measuring requirement.
2. Connect the electrode of tested object to the corresponding jack of the
instrument.
3. Connect Jack G to the protection ring when testing the cable.
4. Press the test switch and the test will be carried out. When the display
value is stable, the reading will be ready. Press the right knob to lock the
continuous test, and turn the left knob to release the continuous test;
when the test switch is pressed, the high voltage red warning light will
light up, the high voltage symbol will appear on the screen, and the
buzzer will sound "Di Di": when the measured insulation resistance is
less than 5% of the range or short circuit, the buzzer will give a long
sound warning.
5. Connect the red test pen "E" to the end of the measured circuit and the
black test pen "L" to the GND end of the measured object; the lead "E"
should be suspended in midair as far as possible.
6. If only "1" is displayed in the top digit, it means the measuring range is
exceeded, and a higher range gear needs to be selected.
Attention:
(1)When the test switch is pressed, the output end "E" will output high
voltage, please be careful.
(2) When testing, check whether the selection of test voltage and the
prompt of test voltage on LCD are consistent with the required voltage.
(3) In MΩ test, the unstable reading may be caused by environmental
interference or unstable insulation material. In this case, the "G" end can
be connected to the shielded end of the tested object to stabilize the
reading.

Diagram of the method to measure insulation resistance
Resistance and Continuity Measurement
1.Turn the knob to the gear of 2000V.
2.Connect the red test pen to the "V/Ω" input end, and connect the black
test pen to the "G" input end.
3.Cross-connected the test rod to the circuit to be measured, and the
data will display on the screen.
4.When the measured resistance is less than 50Ω, the buzzer will make a
sound.
Attention:
(1)If the resistance value exceeds 2KΩ or the open-circuit state occurs,
“1” will be displayed on the screen.
(2)When measuring online resistance, make sure that all the power
supply of the measured circuit has been turned off and all the
capacitance has been fully discharged before carrying out measurement.
(3)Large errors that occur during measurement may be caused by the
influence of other components online or the electric potential at both
ends of the resistance.
(4)Please do not input voltage in resistance measuring range.
DC Voltage Measurement
1.Turn the knob to the gear of 1000V.
2.Connect the red test pen to the "V/Ω" input end, and connect the black
test pen to the "G" input end.
3.Cross-connect the test rod to the circuit to be measured. The voltage
and polarity of the point to which the red test rod connects will be
displayed on the screen.
Attention:
(1)If there is residual number on the screen when measurement has not
started yet, it is a normal phenomenon which will not influence the
measurement. If "1" is displayed on the top digit, it means the measuring
range is exceeded.
(2)Input voltage must not exceed DC 1000V. If so, the circuit of the
instrument may be damaged.
(3)When measuring high voltage circuit, be careful not to touch the high-
voltage circuit.
AC Voltage Measurement
1.Turn the knob to the gear of 750V
2.Connect the red test pen to the“V/Ω”input end, and connect the black
test pen to the “G”input end.
3.Cross-connect the test rod to the circuit to be measured. The voltage
and polarity of the point to which the red test rod connects will be
displayed on the screen.
Attention:
(4)If there is residual number on the screen when measurement has not
started yet, it is a normal phenomenon which will not influence the
measurement. If “1”is displayed on the top digit, it means the measuring
range is exceeded.
(5)Input voltage must not exceed AC 750V. If so, the circuit of the
instrument may be damaged.
(6)When measuring high voltage circuit, be careful not to touch the high-
voltage circuit.
