Withstanding Voltage and Insulation Resistance Tests
When testing finishes
A test will stop under one of the following conditions.
a. If the test time elapses (when TIMER is set to ON).
b. If a current greater than or equal to the upper limit (U-FAIL) or less than or equal to the lower
limit (L-FAIL) is measured.
c. If you press STOP.
After a test finishes, the DANGER LED turns off, and the high voltage output is turned off.
If the test finished under condition a or b given above, the judgment result will be displayed on the
screen.
If the test time has been set

After the test time elapses, the PASS LED lights in green, and the test finishes. The PASS LED remains
lit in green for the length of time specified by Pass Hold. The READY LED then lights in light blue,
and the TOS5300 Series switches to the READY state.

The operations that the TOS5300 Series performs after testing finishes for each judgment condition
are shown below.
