Mode 2: Sensor test (default: OFF)

Note
Sensor Test should only be initiated when the process value is stable. A dramatic change of
level in the vessel could cause a sensor failure message.
The Sensor Test checks the circuitry including the sensor, the signal path from the sensor to
the transmitter, and the transmitter itself. While the sensor test is active, the sensor value
increases by a specific offset. This is verified by the electronics.
There are three methods of activating a sensor test:
• locally, using the keypad
• locally, using a magnet
• remotely, via PROFIBUS PA
Keypad activated sensor test
• Select Mode 2.
• Press ⇑ or ⇓ to start the test.
• After a few seconds, the display shows GOOd or FAILd.
• Press M to exit.
Magnet-activated sensor test
To carry out a test without opening the lid or entering Mode 2, use a magnet.
• Bring the magnet close to the test area indicated on the housing.
• The sensor test starts and finishes automatically after 10 seconds.
• The auxiliary reading displays either SENSOR TEST SUCCESSFUL,
or SENSOR TEST FAILED, as rolling text.
Sensor test using PROFIBUS PA
• Please see Sensor test (Page 79) for details.
Note
Output state does not change when sensor test is initiated.
Test magnet is supplied with the instrument.
