immediately. The HANDLER outputs the FAIL signal and the beeper sounds at the same
time until the STOP key on the tester is pressed. The test result will show the FAIL state.

4.8.3 Procedure for IR Test

1. Connect the UUT following the connection method described above.
2. In the power on screen shown below:

Illustration:
"TEST- 1/2" means there are 2 test steps and the 1
means the test mode. "SOURCE" means the set voltage, "LIMIT" is the low limit set for
the insulation impedance, while "RES." is the test result.
3. Press STOP to prepare for the test. The status line shows "STANDBY".
4. Press START to activate the test.
When this key is pressed the tester starts to output voltage and the DANGER LED is
turned ON. The status line shows a counter to count down. "SOURCE" will show the
output voltage value, "LIMIT" will show the current readings and "RES." will show the test
result.
5. GOOD Judgment
When all the tests are done and the results show PASS, the tester will see the UUT as a
GOOD product and turn off the output. The HANDLER interface outputs the PASS signal
and the beeper sounds at the same time.
6. NO GOOD Judgment
If the test value is abnormal, the tester judges it as FAIL and turns off the output
immediately. The HANDLER outputs the FAIL signal and the beeper sounds at the same
4-26
The measured current exceeds the range or the high/low limit.
The ARC measurement exceeds the set high limit.
