1. The voltage indication on the display refers to the voltage at the DUT (device under test), and the accuracy is according to the DC voltage mea-
surement. The default test voltage is shown in the table below.

The test voltage across a resistor of a value of UN × (1000 Ω/V) shall not differ by more than 10% relative to noload (open) voltage, as a result of
possibly present AC voltage components in the output voltage, when a capacitor of 1 µF is connected in parallel with the insulation resistance to
be measured. UN represents the nominal output test voltage.
2. Additional accuracy is to be added to the basic accuracy as shown in the table below.
