Check if all three switching conditions occur in the correct sequence
and the stated time period. If this is not the case, there is a fault in the
measuring system (see also the operating instructions manual of the
signal conditioning instrument). Keep in mind that connected instru-
ments are activated during the function test. By doing this, you can
check the correct function of the measuring system.
Note:
Keep in mind that the starting time t
the time up to the first switching (e.g. SITRANS SCSC, SITRANS
TCSC +1 s)
