Residual Current Generated by the Tester (TRMS value at 20 ms):
Touch Voltage Uc and Uci
Nominal range per EN 61557-6 – 3.0 to 49.0 V for a touch volt-
age limit value of 25 V
Nominal range per EN 61557-6 – 3.0 to 99.0 V for a touch volt-
age limit value of 50 V
Impedance of the Fault Loop RL
Nominal range per EN 61557-3 – 27
to 2000
Measuring current:

Alternating Voltage (frequency range: 45 to 65 Hz)
Key
a) In the case of alternating quantities, the TRMS voltage value is
measured.
b) The measuring uncertainties specified here are only valid if line
voltage is stable during measurement, the earthing system is
free of interference voltage, there are no influences caused by
potential from neighboring systems and no leakage current
flows through the measured electrical circuit.
c) rdg. means reading, i.e. measured value, D = digits (i.e. num-
ber of the decimal place with the least significance)
