3.4 Displaying the Test Result

Test is unsuccessful when lights up. display will be retained.
(default condition)
To return to the READY state, press the STOP key, which will cancel the FAIL
Hold function.
In normal tests, it takes about 100 ms for the instrument to detect FAIL until the
output voltage is OFF.
3.4.2 "FAIL" Determination
When a current 1.5 times higher than the upper-limit test value is flowing while
performing a withstand-voltage test, the voltage is immediately blocked by the
insulation circuit, resulting in an UPPER FAIL. In such cases, the measured cur-
rent value is not displayed correctly. The current value is not displayed, and
“- - - “ will appear.
To delete the held value shown when the test ended in FAIL.
