Mode
To locate insulation faults, select one of the three available modes for insulation fault
location.
•Manual
In manual mode, the insulation fault location does not start
automatically. If you start the insulation fault location, it
remains active without considering the insulation resistance
and the alarm message of the ISOMETER®.
•auto
In auto mode, the insulation fault location starts automati-
cally as soon as the response value of alarm 2 of the
ISOMETER® has fallen below the preset value. The insulation
fault location is cyclically interrupted for an insulation meas-
urement. If the insulation fault still exists after the interrup-
tion, the insulation fault location starts again. The insulation
fault location only stops if alarm 2 is inactive. If a new insula-
tion fault appears, the insulation fault location restarts auto-
matically.
•1 cycle
In 1-cycle mode, the insulation fault location starts automat-
ically as soon as the response value of alarm 2 of the
ISOMETER® has fallen below the preset value. The insulation
fault location is stopped after one cycle.
If the insulation fault still exists after the interruption, the
insulation fault location does NOT start again. If a new insu-
lation fault appears, the insulation fault location restarts
automatically for one cycle.

Using a portable EDS
If you would like to use a portable EDS, activate this function here. After that, the insula-
tion fault location process will be automatically adjusted.

Scanning channels
For a successful insulation fault location, all active measuring channels must be deter-
mined. Indicate if you would like to start the search for EDS measuring channels.
Also refer to
“Commissioning EDS” on page 35
Do not carry out a manual test during a manually started insulation fault
location, since the insulation fault location would be aborted by that.
•on
Insulation faults can be located with a portable EDS.
•off
Insulation faults cannot be located with a portable EDS
If the trigger mode is set to "auto", the use of a portable EDS must be acti-
vated in the menu as the measurement method is correspondingly adjust-
ed at this menu point (also refer to
•Cancel
Aborts the scan process.
•Start
Starts the scan process (search) for EDS channels.
If one bus device fails, the ISOMETER® asks whether it should search for
measuring channels and then automatically determines all channels
again. Also refer to
