NOTE
For evaluation purposes, the first measured value and the
values documented during previous maintenance or safety
checks must be compared to the measured values.
A sudden or unexpected increase of the measured values
may indicate that a fault has occurred in the primary circuit
of the power supply (damaged insulation, water or humidity
damage, defective interference suppressor, etc.) - even if the
limit value of 2.5 mA is not exceeded.
