6.11.1 Navigating in the menu
6.11.2 Menu item: Settings
Using this menu item you can access the following parameters for the insulation fault location and
for the residual current measurement to:

Set the response value for the locating current I
Δ
L
measured with the measuring clamp to
between 0.2…10 mA.
This value range is equally suitable for control circuits (0.2…1 mA) and main circuits (2…10 mA).
On the usage of the locating current injector note that the permissible locating current defined
for control circuits is
I
Lmax
= 5 mA, while for main circuits it is I
L max
= 50 mA.

Set the response value for the residual current I
Δ
n
measured with the measuring clamp to
between 10 mA and
10 A

Activate or deactivate the fault memory

Activate or deactivate audible signalling of alarms

Set the frequency of the system monitored

Enable the indication of the harmonics to display the current for the harmonic with the greatest
amplitude in the standard display. All harmonics from H1 to H8 can be checked using menu
item "4. Harmonics", see also page 41. Note that with harmonics activated only system frequen-
cies of 50 Hz and 60 Hz can be selected.
