4.2 Troubleshooting

4.2.1 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.

4.2.1.1 Voltage present before an insulation measurement

4.2.1.2 Range exceeded during 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 to the left, and no
measurement is taken.
You must eliminate the voltage to
resume taking the measurement.
If during an insulation measurement
the value to be measured exceeds the
measurement range (which depends
on the instrument and the test voltage),
G
M mAµA
the instrument reports this condition.
For example, the screen to the left is
G
displayed when the range is exceeded
on the Model 6524 while measuring in
the 100V range.
