12 Characteristic Values
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, patient
leakage current
4
Protective conductor current, touch current, device leakage current
5
Only with SECUTEST BASE10 (feature G01) or SECUTEST PRO
6
Only with SECUTEST PRO (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.
Key: rdg. = reading (measured value), d = digit(s)
Test Times, Automated Sequence
Test times (“measurement duration” parameter) can be set sepa-
rately 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 take place during leakage current measurement with clamp
meter or adapter.
