19 Characteristic Values
Please refer to chapter 1.2 on page 7 to check as to which of the following measurements is required for the relevant regulation
1
As of 25 mA: shutdown by residual current measurement within 100 ms
2
Exception earth leakage current: only 0.000 … 3.100 mA
3
Measuring circuit is highly resistive, indication at display
4
Measurement with AC test current (Feature G00 or G01) is not possible at the
sockets (1 through 3).
Feature G01 or SECULIFE ST
HV: > 25 A; Short-circuit current is less than 25 A if the
SC5 special cable is used.
5
Test duration max. 40 s, protection against overheating: measurement cannot be
restarted until a waiting period of 1 minute has elapsed.
6
Calculated value
7
AC and DC are measured for patient leakage current and patient auxiliary current.
8
The data are only valid for the values displayed at the test instrument. Data which
are transmitted via the RS232 interface may deviate.
9
only applies to earth leakage current or mains at application part
Key: of rdg. = of reading (measured value), D = digit
