played on the LCD.
To cancel the protection function, turn off the POWER switch, and check the AC
line and the settings on the tester.
■
Output-voltage monitoring function
When the output voltage deviates from ±(10 % of the s50
V
), the protection
function activates. “
V
OLT ERROR” flashes on the LCD, and the test stops.
To cancel the protection function, press the STOP switch.
In insulation resistance testing, however, the test continues if LOWER is set to OFF.
In this case, the measured voltage flashes on the LCD voltmeter to indicate the
