VEGAMET 625 • Double channel HART
28970-EN-130701
The following illustrations and examples relate to the min./max. ad-
justment of a radar sensor with HART communication.
1. With [OK] you prepare the percentage value for editing, with [->]
you place the cursor to the requested position. Set the requested
percentage value with [+] and save with [OK].
2. After entering the percentage value for the min. adjustment, the
suitable distance value must be entered. If you want the use the
currently measured distance value, select the menu item "Accept"
(live adjustment or adjustment with medium). If the adjustment
should be carried out independent of the measured level, then
select the option "Edit". Enter now the distance value in m [m(d)]
for the empty vessel that is suitable for the percentage value, e.g.
distance from the sensor to the vessel bottom (dry adjustment or
adjustment without medium).
3. Save your settings with [OK] and move to "Max. adjustment" with
[->].
4. As described previously, enter now the percentage value for max.
adjustment and confirm with [OK].
5. After entering the percentage value for the max. adjustment, the
suitable distance value must be entered. If you want the use the
currently measured distance value, select the menu item "Accept"
(live adjustment or adjustment with medium). If the adjustment
should be carried out independent of the measured level, then
select the option "Edit". Enter now the distance value in m [m(d)]
for the full vessel that is suitable for the percentage value (dry
adjustment or adjustment without medium). Keep in mind that the
max. level must be below the radar antenna.
6. Finally save your settings with [OK], the adjustment is finished.
Keep in mind that this adjustment refers only to the measurement
loop selected by you initially. All other measurement loops must
be adjusted separately, if necessary.
To suppress fluctuations 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 sufficient to smooth the measured value display.
