Note: After using the tester for the first time or not using the tester for a long
time, the tester may fail to start up because of low battery. Please charge the
tester for a period before trying to start up.
Please charge as below methods:
Plug one end of the power adapter into the DC IN charging jack
of the tester and connect the other end to the AC power outlet. If
the charging indicator on the tester lights up in red, it indicates
charging, the indicator lights up in green after fullly charging.
2.1.2 Turn On/Off
In the shutdown state, long press the Power button on the tester
until the TEST button is lit, the tester will be initialized and
powered on, and the system will have a buzzer prompt.
To shut down, long press the Power button on the tester for 3
seconds until the screen is off.
The tester will automatically shut down when it is not operated for
more than 15 minutes in the resistance measurement mode. If
the tester is in the voltage measurement mode, it needs to be
shut down manually.
Note: To ensure safety, the tester will automatically shut down when charging.

Note:
Do not input a voltage higher than 600V or 600Vrms. Measuring higher
voltages risks may damage the tester.
Special attention should be paid to avoid electric shock when measuring high
voltages.
After completing all measurement, disconnect the test clip from the circuit to
be tested and remove the test clip from the tester input.
If the voltage measurement exceeds the maximum range, the buzzer will
sound.
2.3.2 Insulation Resistance Measurement
Note: The continuous measurement mode is by default for insulation
resistance measurement during startup.
(1) Before measuring insulation resistance, the circuit to be
measured must be completely discharged and isolated from
the power circuit.
(2) Insert the red test clip into the LINE port, the black test clip
into the GUARD port, and the green test clip into the EARTH
port.
(3) Connect the red and green alligator clips to the measured

object and output the voltage from the LINE port.
(4) Select the following insulation resistance measurement mode.
After the system is powered on, the system enters the
insulation resistance continuous measurement mode by
default. Press / to select the output voltage and press
TEST for 1 second to start measurement. At the same time,
the buzzer will sound. The measured insulation resistance
value will be displayed on the screen.
Press the TIME button to select the fixed-time measurement
mode. Fixed-time measurement prompt and timing symbols
will be displayed on the screen. Press the / buttons to
adjust the output voltage and press the / buttons to set the
timing duration (setting range from 00:10 to 15:00). Press the
TEST button for 1 second to start the fixed-time measurement.

The timer area of the screen starts to display a countdown.
The system will automatically end the measurement at the set
time.
Press the COMP button to enter the insulation resistance
comparative measurement mode, and the comparative
measurement prompt will appear on the screen. Press the
/ buttons to select an output voltage and press the /
buttons to set the comparative resistance (setting range:
10MΩ ~ 900GΩ). Press the TEST button for 1 second to start
the measurement. If the insulation resistance measurement
value is smaller than the resistance comparative value, the
"FAIL" prompt will be displayed in the lower left corner of the
screen; otherwise, the "PASS" prompt will be displayed.
Note:
Before the test, ensure that the circuit to be measured is not electrified. Do
not measure the insulation of electrified equipment or circuit.
The tester has dangerous voltage output. Please be careful while operating.
Never press the TEST button to output the high voltage before ensuring that
the tested circuit is firmly clamped and the hand is off the test clamp.
Do not short circuit two test clips or measure the insulation resistance under
the high voltage output. This operation is easy to spark and cause fire, and
damage the tester.
If the resistance measurement exceeds the maximum range, the buzzer will
sound.
