Contact current The following points must be observed during the contact current measurement:
- Do not perform the measurement until the ground conductor current measurement
has been carried out successfully
- The device must be in charge mode
The measurement is taken between a grounded point and the conductive part that can
be touched and that is not connected to the ground conductor.
The contact current must not exceed 0.5 mA.
