VEGA VEGAPULS series 60 Recurring function test - Manual (Page 13)

If all the above conditions are fulfilled, the measurement works
correctly and the verification of the echo data was successful.
Continue with the next test point.
3 .5 Sensor reaction to a level change
With this test point, you monitor the reaction of the sensor during a
level change.
1 Set the indication of the sensor DTM to "Distance".
2 Change the filling of your vessel.
It doesn't matter if you fill or empty the vessel.
The filling speed is also not relevant.
The level change must be at least 50 mm.
3 Take note of the sensor reaction.
Does the measured value [m(d)] move in the correct direction
during emptying/filling?
The displayed measured value (distance) is the distance between
seal surface of the sensor and the product surface.
● The measured value will decrease during filling.
● The measured value will increase during emptying.
When the level value changes analogue to the level change, the
measurement works correctly and the assessment of the sensor
reaction was successful.
If all function tests were successful, the recurring function test is
finished.
If you used an mA-meter for the recurring function test, switch off the
sensor and remove the mA-meter from the sensor cable after finishing
the recurring function test.
