The measuring range upper limit depends on the selected test voltage.
10
Due to inrush current limiting components, the voltage at the test socket may be
lower than the measured line voltage.

Key: rdg. = reading (measured value), d = digit(s)
Test Times, Automated Sequence
The test times (parameter „Measurement duration ...") can be adjusted
in the sequence parameter setting menu for each rotary switch posi-
tion separately. The test times are not tested and calibrated.
Emergency Shutdown During Leakage Current Measurement
As of 10 mA of differential current (can also be set to 30 mA), automatic
shutdown ensues within 100 ms. This shutdown is not effected during
leakage current measurement with clamp or adapter.
