Semi-automatic Change of Fault Simulations (Statuses)
As an alternative to changing
manually between the fault sim-
ulations via the parameter menu
of the respective PRCD selec-
tion PRCD-S 1~, PRCD-K 1~ or
PRCD-S 3~ at the test instru-
ment, it is possible to switch
quickly and conveniently
between the fault simulations.
Select status parameter AUTO
for this purpose. After replying
to and storing each visual
inspection, an automatic
switch-over to the next fault simulation takes place. Individual fault
simulations can be skipped by pressing key I
N
at the test instru-
ment or at the test plug.
