VEGA VEGAPULS 45 4 … 20 mA; HART compact sensor - Manual (Page 6)

6 VEGAPULS 42, 44 and 45 – 4 … 20 mA
1.3 Adjustment
Every measurement set-up is unique. For
that reason, every radar sensor needs some
basic information on the application and the
environment, e.g. which level means "empty“
and which level "full“. Beside this "empty and
full adjustment“, many other settings and
adjustments are possible with VEGAPULS
radar sensors.
The adjustment and parameter setting of
radar sensors is carried out with
- the PC
- the detachable adjustment module MINI-
COM
- the HART ® handheld
Adjustment with the PC
The set-up and adjustment of the radar sen-
sors is generally done on the PC with the
adjustment software PACT
ware TM . The pro-
gram leads quickly through the adjustment
and parameter setting by means of pictures,
graphics and process visualisations.
Adjustment with the PC on the analogue 4 … 20 mA
signal and supply cable or directly on the sensor
