VEGA VEGADIF 55 4 … 20 mA_HART - Manual (Page 77)

MEASURING MODE: S elect option "Pressure".
GROUP SELECTION: S elect QUICK SETUP menu.
POS. ZERO ADJUST: D ue due the installation position of the
instrument, a shift of the measured value can be caused. Correct the
MEASURED VALUE
via the parameter POS. ZERO ADJUST with the
option "Accept", i.e. assign the value 0 to the existing pressure.
SET LRV: S et measuring range (enter 4 mA value). Enter pressure
value for the lower current value (4 mA value). A reference pressure on
the instrument is not necessary. Set measuring range (enter 4 mA
value).
SET URV: S et measuring range (enter 20 mA value). Enter pressure
value for the upper current value (20 mA value). A reference pressure
on the instrument is not necessary. Set measuring range (enter 20 mA
value).
DAMPING VALUE: E nter the damping time (time constant τ). The
damping influences the speed with which all following elements such
as e.g. local indication, measured value and current output react to a
pressure change. Enter the damping time (time constant τ).
Measured value indication: S elect Quick SETUP menu.
