PCC Protective conductor current measurement
Measurement method Measures the voltage drop across a reference resistance that is inserted
in the middle of the protective earth wire and measure the PCC.
METER Measures the current flowing through measurement terminals A and B or
the applied voltage (cannot be measured simultaneously).
Measurement
method Current mea-
surement Uses a measurement network representing the human body impedance,
measures the voltage drop across the reference resistance, and calcu-
lates the current flowing through terminals A and B.
Voltage mea-
surement Measures the voltage applied between measurement terminals A and B.
Measurement
mode
(MODE) DC Measures only the DC component by eliminating the AC component.
RMS Measures the true rms value.
PEAK Measures the waveform peak value.
