6 Setup with the integrated display and adjustment unit
VEGAMET 625 • Double channel HART
28970-EN-150129
Before carrying out the adjustment, the requested adjustment unit can
be selected which depends on the sensor type. With radar, ultrasonic
and guided microwave this is always the distance in metres or feet
"m(d)"or"ft(d)",andwithpressuretransmittersitise.g."bar"or"psi".
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conrm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nished.
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.
