You can obtain further information on the settings in the ARGUSpedia on the 
instrument.

When Isolation resistance measurement is started, a warning is displayed 
when a measurement voltage of 105 V is used. 

The ARGUS generates a voltage of 105 V at the start of the measurement.

Special care is necessary due to this generated voltage.
