TC Touch current measurement
Measurement mode Uses a measurement circuit network representing the impedance
of a human body and measures the voltage drop across a
reference resistance to calculate the touch current.

PCC Protective conductor current measurement
Measurement method Measures the voltage drop across a reference resistance inserted
in the middle of the protective ground line to calculate the
protective conductor current. The measurement impedance is
150
Ω.
Patient Patient leakage current measurement
Measurement method Uses a network conforming to IEC 60601 and measures the
voltage drop across a reference resistance to calculate the patient
leakage current.
Meter Measures the current flowing or voltage applied across the A and
B terminals (simultaneous measurement not possible).
Measurement
method
Current
measurement
Uses a measurement circuit network representing the impedance
of a human body and measures the voltage drop across a
reference resistance to calculate the current flowing across the A
and B terminals.
Voltage
measurement
Measures the voltage applied across the A and B terminals.
Current measurement mode DC Eliminates AC components and measures only the DC
component.
RMS Measures the true rms value (switch AC and AC+DC)
Peak
1
Measures waveform peak values
1 Current measurements may not be stable due to the effects of the power supply line waveform or the wiring
environment between the product and the EUT.
