This test is valid if you cannot change the vessel filling or cannot

dismount the sensor.

With the SITRANS SCSC or SITRANS TCSC2 signal conditioning

instrument, the test result can be checked directly on an LED on the

signal conditioning 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 SITRANS SCSC and

SITRANS TCSC signal conditioning instruments. 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.

Make sure the connected downstream devices are activated during

the function test.

•

Failure LED lights red - test not passed- Please check the com-

plete measuring system.

•

Failure LED remains dark - test passed. The proof test is hence

finished.
