Notes:
Ì The appliance is connected to the mains voltage. Make sure that the appliance
with moving parts is safely mounted or protected to prevent possible danger to
operator or damage to the appliance!
Ì Consider any displayed warning before starting measurement!
Ì The instrument automatically changes L/N polarity of connected appliance.
5.5 Touch leakage current
This test determines the current that would flow if a person touches the appliance.
Measurement is based on a human body model with resistance of 2 kΩ and frequency
weighted for perception / reaction according the standards IEC 60990 and VDE 0404-3.
Both AC and DC components of touch leakage current are detected.
The instrument measures the leakage current flowing through the S probe into earth.
The appliance under test can be powered from the mains test socket or directly from the
installation (fixed installed equipment).
The instrument measures touch leakage current for both polarities of L and N.
