Voltage and frequency
Reference value Accuracy
50.0 V @ 240 V a.c.
47.9 V @ 230 V a.c.
± (5 % + accuracy of mains
voltage)
Short-circuit current: <6 mA.
Nominal output resistance: 25 kΩ.
Specified accuracy is valid only if Eurocheck output is enabled.
Fault loop impedance, trip-lock impedance, line impedance
Reference value (Ω)*
Accuracy
1.2 (LOOP+1 Ω) ±0.2 Ω
11.0 (LOOP+11 Ω) ±0.5 Ω
* This value is added to the actual loop/line impedance. Mains voltage fluctuations affect
accuracy of the reference.
Loading at 240 V a.c.: max. 3 minutes, 25 % duty ratio.
RCD trip-out time simulation and IΔn current measurement
IΔn reference value Accuracy
30 mA
±1 %
Trip-out time reference value Accuracy
50 ms
±2 ms
CURRENT LO indication Accuracy
28 mA
±1 mA
CURRENT HI indication Accuracy
35 mA
±1 mA
Automatic reset after 3 seconds.
Automatic mains polarity verification
Test is performed in 2 seconds after connection of Eurocheck to mains socket.
Note about reference values
Instead of relying on accuracy specifications given in this chapter, it is possible to use
calibrated reference values noted in Eurocheck Production validation certificate. They
express lower uncertainty, thus enabling better evaluation of tested instrument.
Note about EN and IEC standards
Text of this manual contains references to European standards. All standards of EN
6xxxx (e.g. EN 61010) series are equivalent to IEC standards with the same number
(e.g. IEC 61010) and differ only in amended parts required by European harmonization
procedure.
