Operating Steps:
Must wear rubber insulation gloves, seat under the rubber insulation pad!Only when the test lamp is off
and there is no high voltage output can the test object be connected or disassembled!
1. Connect the object under test and make sure that the voltmeter indicates "0" and the test lamp is off.If
it is AC test, select the AC high-voltage output hole connection test line; if it is DC test, select the DC
high-voltage output hole connection test line and connect the ground line;2. Set the value required for
leakage current test;
1) press the preset/test switch;
2) select the current range, 0 ~ 2mA range or 2mA ~ 10mA range;
3) adjust the required leakage current alarm value;
4) pop the preset/test switch.3. Manual test:
1) set the timing switch to the off state. If it is AC test, the AC/DC switch will pop up. If it is DC test, press
the AC/DC switch.Press the start button, the test light will be on, and turn the voltage adjustment button
to the required indicating value;
2) if the leakage current index of the measured object exceeds the specified leakage current value, the
instrument will automatically cut off the output voltage, and the buzzer will give an alarm, and the
over-leakage indicator light will be on. At this time, the leakage current index of the measured object is
unqualified. Press the reset key to eliminate the alarm sound.On the contrary, the leakage current index
of the measured object is qualified.
Timing test:
1) press the time switch to adjust the value of the time timer and set the required test time value;
2) set the alarm value of leakage current and press the start button to adjust the voltage to the required
test value;
3) if the timing time is up, the test voltage is cut off and the test lamp goes out, then the leakage current
index of the tested object is qualified;If the current is too large, the over-leakage light will be on in the
timing process and the buzzer will give an alarm. The leakage current index of the measured object is
unqualified. Press reset
Key to eliminate the alarm sound.
Caution:
1. The operator must wear rubber insulating gloves and put rubber insulating pads under the seat to
prevent high-voltage electric shock;
2. The instrument must be reliably grounded;
