Note:
Keep in mind that the starting time t
A
of the voltage supply can extend
the time up to the first switching (e.g. VEGATOR 636: +1 s)
Test procedure
After releasing the button or after a brief line break.

This test is valid if you cannot change the vessel filling or cannot
dismount the sensor.
With the VEGATOR 121 or 122 signal conditioning instrument, the
test result can be checked directly on an LED on the signal condition-
ing instrument.
This is the most comfortable and simple way to carry out the test.
A test key is lowered in the front plate of the VEGATOR 121, 122
signal conditioning instrument. Push the test key for > 2 seconds with
a suitable object. Hence a test is started. The sensor must neither be
dismounted nor triggered by filling the vessel.
