GMC-I Messtechnik GmbH 103
2
Known as equivalent leakage current or equivalent patient leakage current from pre-
vious standards
3
Protective conductor current, touch current, device leakage current, patient
leakage current
4
Protective conductor current, touch current, device leakage current
5
Only with feature F01
6
Only with feature I01
7
Measurement types IPE_clamp and IG_clamp
8
Measurement type IPE_AT3 adapter and IG_AT3 adapter
9
The upper range limit depends on the selected test voltage.
10
Voltage at the test socket may be lower than measured line voltage due
to components which limit inrush current.
11
Only with feature G02
Key: rdg. = reading (measured value), d = digit(s)
Testing Times, Automatic Sequence
Testing times (“measurement duration” parameter) can be set separately
for each rotary switch position during configuration of the sequence
parameters. Testing times are neither tested nor 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 500 ms. This shutdown does
not take place during leakage current measurement with clamp
meter or adapter.
