Take note that the connected instruments are activated during the
function test.
You can find the coverage of the test in the Safety Manual.
If this does not cause any problems, you can fill the vessel up to the
switching point and monitor the correct sensor reaction.
Procedure
1. Separate the instrument briefly (>2 s) from voltage supply.
After switching on again, the instrument must take on the same
switching status.
If this is not the case, then there is a fault in the measuring sys-
tem.
Take note that the connected instruments are activated during the
function test.
2. Push the mode adjustment (min./max.)
Check if the switching condition changes (signal lamp - switching
condition). By doing so, you can check the correct function of the
measuring system.
If this is not the case, then there is a fault in the measuring sys-
tem.
Take note that the connected instruments are activated during the
function test.
