4. DANGER light stops flashing after the end of offset.
4.5.2 Sampling Operation of Standard Capacitor
1. Before Open Short-Circuit check mode (OSC) testing or testing a new capacitor DUT or
replacing a capacitor DUT, the standard capacitance value must be sampled first, or input a
capacitor value as the standard value.
2. Offset on the TEST interface first before sampling the standard capacitor value. Each time the
test cable or fixture is replaced, the offset must be performed to ensure the accuracy of the test.
3. When sampling the standard capacitance value, first use the standard sample of the capacitor to
be tested as the DUT, and measure the capacitance value according to the sampling in OSC mode as
the standard value for testing.
4. When performing the open short circuit check mode (OSC) test, the condition to judge the
OPEN/SHORT is according to the sampled capacitance value.
4.5.3 Method of Connecting the DUT
1. First make sure that the tester has no voltage output and the DANGER indicator not lit nor
flashing.
2. Then connect the test cable for low potential to the RTN/LOW or HV2 terminal of the tester,
short circuit this test cable to the high voltage test cable and insert the high voltage test cable into
the high voltage output terminal HV1 to make sure that there is no high voltage output.
3. Finally, connect the test cable of low potential (RTN/LOW or HV2) to the DUT first and then
connect the test cable of high potential HV1 to the DUT.
4.5.4 Test Procedures
4.5.4.1 AC/DC/IR Test Procedures
1.
Connect the DUT correctly according to the connection method of the DUT.
Press

〗
key to enter the measurement interface, at this time, the pending test steps that have
been set up are displayed, the small font shows the test step, test mode and test voltage,
withstanding voltage test shows current upper limit value, insulation resistance shows resistance
lower limit value. The middle large font shows the set voltage, current and time.
2.
Press the

key to prepare for the test.
Press the
【
START
】
key to start the test, when this key is pressed, there will be a high voltage
output, and the DANGER light flashes.
Warning: At this time, it is in the test state and there is a
large voltage output.
The first line in large font shows the actual measured high voltage output
value, the second line is the measured current value or resistance value, the third line is the
corresponding time, there is message prompt in the lower left corner.
3.
Pass Judge
When all the test modes are completed and the test result in the lower right corner displays PASS, it
is judged as pass and cut off the high voltage output, the rear panel also gives a pass signal, the
buzzer simultaneously acts.
