The ISOMETER® has two modes of operation: GEn and DC. The required ope-
rating mode is selected in the "SEt" menu.
3.1 GEn mode
GEn mode is used in AC/DC or in DC systems. In this mode, the ISOMETER®
achieves the maximum response time of

3.2 DC mode
DC mode is used in DC systems only. In the event of an asymmetrical fault in
this mode, the ISOMETER® achieves the maximum response time of

In the event of an alarm message on the ISOMETER®, the
insulation fault should be eliminated as quickly as possible.
If the ISOMETER® is installed inside a control cabinet, the
insulation fault message must be audible and/or visible to
attract attention.
