Description
CHECK CALIBRATION
Measurement result is negative probably because of
shorter test leads than calibrated (negative value is higher
than 5 digits).
Calibrate test leads again!
EXTERNAL VOLTAGE
External voltage higher than 3 V is applied between two
R
PE
or between two SENSE test terminals
(measurement is not running) or higher than 10 V
(measurement is running).
External voltage higher than 5 30 V is applied between
any R
PE
or SENSE test terminal and GND.
Remove external voltage!
