Tosuppressuctuationsinthemeasuredvaluedisplay,e.g.caused

by an agitated product surface, an integration time can be set. This

time can be between 0 and 999 seconds. Remember that the reaction

time of the entire measurement will then be longer and the sensor will

react to measured value changes with a delay. In general, a period of

afewsecondsissucienttosmooththemeasuredvaluedisplay.

Enter the requested parameters via the appropriate keys and

save your settings with [OK].

Alinearizationisnecessaryforallvesselsinwhichthevesselvolume

does not increase linearly with the level, for example, with a cylindrical

orsphericaltank.Correspondinglinearizationcurvesareprepro-

grammed for these vessels. They represent the correlation between

the level percentage and vessel volume. By activating the appropriate

curve, the volume percentage of the vessel is displayed correctly. If

the volume should not be displayed in percent but e.g. in l or kg, a

scaling can be also set.

Enter the requested parameters via the appropriate keys and

save your settings with [OK].

Scaling means converting the measured value into a certain param-

eterandunit.Thelinearizedpercentagevalueisthesourcesignal

which is used as basis for the scaling. The indication can then show

the volume in litres e.g., instead of the percentage value. Indication

values from max. -99999 to +99999 are possible.

Enter the requested parameters via the appropriate keys and

save your settings with [OK].

In this menu item you can enter an unambiguous designation for each

measurement loop, e.g. the measurement loop name or the tank or

product designation. In digital systems and in the documentation

of larger plants, a singular designation should be entered for exact

identicationofindividualmeasuringpoints.
