GMC-I Messtechnik GmbH 77
1
Specified values are only valid for the display at the test instrument. Data
transmitted via the USB port may deviate from these values.
2
Known as equivalent leakage current or equivalent patient leakage current
from previous standards
3
Protective conductor current, touch current, device leakage current, pa-
tient leakage current
4
Protective conductor current, touch current, device leakage current
5
Only with SECUTEST BASE10 (feature G01), SECUTEST PRO or SECULIFE ST BASE
6
Only with SECUTEST PRO (feature I01) or SECULIFE ST BASE
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
Due to inrush current limiting components, the voltage at the test socket
may be lower than the measured line voltage.
11
SECULIFE ST BASE 25 only
Key: rdg. = reading (measured value), d = digit(s)
Test Times, Automated Sequence
Test times (“measurement duration” parameter) can be set separately
for each rotary switch position during configuration of the sequence
parameters. Test 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 100 ms. This shutdown does
not tak
e place during leakage current measurement with current
clamp sensor or adapter.
