VEGABAR 54 • 4 … 20 mA/HART
36726-EN-130321
Information:
The zero adjustment shifts the value of the span adjustment. The
span, i.e. the difference between these values, however, remains
unchanged.
Information:
For an adjustment with pressure, simply enter the actual measured
value indicated at the bottom of the display.
If the adjustment ranges are exceeded, the message "Outside param-
eter limits" appears. The editing procedure can be aborted with [ESC]
or the displayed limit value can be accepted with [OK].
Proceed as follows:
1. Edit the mbar value in the menu item "span" with [OK].
Span
100.0 %
P
=
+1000.0 mbar
0000.0 mbar
Information:
The displayed pressure for 100 % corresponds to the nominal meas-
uring range of the sensor (in the above example 1 bar = 1000 mbar).
2. Set the requested mbar value with [->] and [OK].
3. Confirm with [OK] and move to the menu overview with [ESC].
The span adjustment is finished.
Information:
For an adjustment with pressure, simply enter the actual measured
value indicated at the bottom of the display.
If the adjustment ranges are exceeded, the message "Outside param-
eter limits" appears. The editing procedure can be aborted with [ESC]
or the displayed limit value can be accepted with [OK].
This function enables reading out parameter adjustment data as well
as writing parameter adjustment data into the sensor via the display
