voltmeter is ensured to “0” and the indicator light for testing is switched off, and its
grounding line is inserted under the earth;
1.The required testing value of leakage current is set:
(
1
)
Press the Preset switch;
(
2
)
Choose the range of the required alarm current;
(
3
)
Adjust the preset potentiometer for leakage current to the required alarm value;
(
4
)
Reset the preset switch;
2.Test Manual:
(
1
)
The timing switch is set to the “OFF” position, the button “start” is pressed, and the
“Test” indicator lights. The knob “Voltage Adjustor” is screwed to the required indicator
value;
(
2
)
After the testing finished, the voltage is adjusted to the 1/2 position of the testing
value and then the button “Reset” is pressed. The voltage output is shut off and the
indicator light is switched off. It proves that the measured object is good;
(
3
)
If the current passing the measured object is greater than the specified leakage
current, the instrument cut off the output voltage automatically, and simultaneously the
buzzer gives out a alarm with sound and light, the overrun indicator light is activated. Here,
the measured object is not eligible. The button “Reset” is pressed and then the alarm can
be cancelled;
3.Timing Test
①
While the “Timing” switch is “ON”, the time preset catch plate is dialed to set the
required value of dwell time;
②
The button “start” is pressed and the voltage is adjusted to the required testing value;
③
When the timing is over, the testing voltage is shut off. It proved that the measured is
good; if the current is greater, prior to the preset time, the overrun indicator light is
activated and the buzzer gives out a alarm, and thus the measured object is bad
.
