5.2.5 Measuring principle
The test standards enable you to choose between various measuring principles to ascertain
the leakage currents. If you have selected one of methods F1 ... F3, a note about the
measuring principle will appear on the screen. The current measuring principle is identified
by “
√
”.
Example: “F3: Direct measurement” and “F4: No insulation measurement”.
F1 ... F3 The DUT can only have one of these features. It is for this reason that only one
of these three menu items can be selected.
F4 During insulation measurement, a voltage of 500 V is applied between the
active conductors and earth. Insulation testing may damage sensitive
devices. Only activate insulation measurement if permitted by the
manufacturer’s instructions provided with the DUT.
