Voltages outside the specified frequency range (e.g. direct voltage) cannot
be measured.
Fault Current Circuit Breaker Test (RCD)
With/without tripping, with/without selective (x2), with/without probe, x5 and ramp function for
determination of the tripping current
Measuring method: Lowering of voltage (without probe) or current-voltage
measurement (with probe) as per IEC 61557-6
