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 and SECUTEST XTRA with feature G01
Key: rdg. = reading (measured value), d = digit(s)
Test Times, Automated Sequence
Test time > 2 s, exception: device protective conductor resistance 
RPE: > 7 s. Test times are not checked or calibrated, but rather 
determined on the basis of processor cycle times.
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.
