RCD-Test:
Nominal Voltage: 230 V, +10 % -15 %, (50...60 Hz)
Measurement time: approx. 2s, approx. 31s (selektive RCD/FI),
max. 18s (measurement of trip current)
Current switch-off: immediately at RCD tripping or at true excess of contact voltage limit.
The protective conductor must be free of noise voltage.
Measurement of Contact Voltage UB:
Measurement current: 1/3 nominal fault current I∆N
Measurement duration: < 100 ms, when exeeding limits immediate measurement
Measurement Range: 1...100 V
Resolution: 1 V
Tolerance: -0%...+10%, +5 Digit
Threshold values: VL selection between 25V / 50V
Contact voltage is measured at 1/3 I∆N and may be extrapolated to nominal current I∆N or double nominal
current 2 I∆N for time delayed residual current circuit breakers.
Measurement of Ground Resistance:
Nominal fault Current I∆N: 10, 30, 100, 300, 500mA standard 100, 300, 500mA selectiv
Measurement current: 1/3 nominal fault current I∆N
Measurement duration: < 100 ms, when exeeding limits immediate measurement
Measurement range: 10 ... 1999 Ω, 0,20 ... 10,00 kΩ at I∆N = 10mA, 30mA.
Display range: 1...1999 Ω, 0,01...10,00 kΩ
Maximum RE is defined by the contact voltage limit VL. For UB > 2x UL, the measurement is interrupted
and, thus, no measurement values can be obtained.
Resolution: 1 Ω, 0,01 kΩ
Tolerancy: ± (6% v. M. + 10 digit)
* Maximum RE is defined by the contact voltage UB. For UB>UL, the measurement is interrupted and, thus,
no measurement values can be obtained.
