Troubleshooting – Errors
During instrument operation, errors may be displayed on the LCD. The causes of any errors must be
corrected before the instrument can resume normal operation.
Voltage Present Before an Insulation Measurement
Before taking an insulation measurement, the instrument measures voltage on the system under test. If
it detects voltage in excess of 25V and you attempt to take a measurement, the instrument displays the
message shown below, and no measurement is taken.
You must eliminate the voltage to resume taking the measurement.
Range Exceeded During an Insulation Measurement
If during an insulation measurement the value to be measured exceeds the measurement range,
the instrument reports this condition. For example, the screen below is displayed when the range is
exceeded while measuring in 100V range.
