Dependingonwhetheryoustartedwithafulloranemptyvessel,you
havetocontinueemptyingorllingthevessel.
Carryoutsuchalinearisationwithseveraldierentllingheightseven
if you have a linear vessel.
A maximum of 32 linearisation points is possible.
In this menu item you can adjust the damping of the sensor. With

1 and 1200 seconds. Keep in mind that the reaction time also in-

Generallyatimeofapproximately60secondsissucienttosmooth
the measured value indication.
Radiationfromexternalsourcescaninuencethemeasuringresultof
the sensor.
Possibleexternalradiationsourcescanbe,forexample,aweldjoint
test on a neighbouring facility or other radiometric instruments.
AnX-rayalarmistriggerediftheimpulses(ct/s)aremorethan25%

This fault message is only output for the period of the increased X-ray
radiation. Then the fault message is automatically reset.
In this menu item you can determine the behaviour of the sensor
whenexternalradiationsourcesappear.
In this menu item you can activate the relay output and determine its
functionaswellastheswitchingpoints.
When the output of the process values is set, you can choose be-
tweenoverllanddryrunprotection.
The relay outputs of the sensor react accordingly.
You can choose " no" reference value. In this case, the relay output
operates as fail safe relay.
This does not apply if " X-ray alarm" is selected as reference value. In
this case the fault message is not active.
Caution:
Independentoftheselectedreferencevalue,therelaywilldeenergize
in case of failure.
Exceptwith"X-ray radiation" as reference value. In this case a failure
signal is not active.
