Deltabar M 4...20 mA HART Commissioning
Endress+Hauser 29
Description
1 Perform "position zero adjustment" → ä 24.
P01-xxxxxxxx-05-xx-xx-xx-011
Calibration with reference pressure (wet calibration)
1 See Table, Step 7
2 See Table, Step 8
2 Select the "Level" measuring mode via the "Measuring
mode (005)" parameter (→ ä 23).
Menu path: Setup → Measuring mode
3 Select a pressure unit via the "Press eng. unit"
parameter, here "mbar" for example.
Menu path: Setup → Press. eng. unit
4 Select the "In pressure" level mode via the "Level
selection" parameter.
Menu path: Setup → Extended setup → Level →
Level selection
5 Select a level unit via the "Output unit" parameter, here
"m" for example.
Menu path: Setup → Extended setup → Level →
Output unit
6 Select the "Wet" option via the "Calibration mode"
parameter.
Menu path: Setup → Extended setup → Level →
Calibration mode
7 a. The hydrostatic pressure for the lower calibration
point is present at the device, here "0 mbar" for
example.
b. Select the "Empty calib." parameter.
c. Enter the level value, here "0 m" for example.
Confirming the value means you assign the
pressure value present to the lower level value.
Menu path: Setup → Extended setup → Level →
Empty calib.
8 a. The hydrostatic pressure for the upper calibration
point is present at the device, here "300 mbar"
(4.5 psi) for example.
b. Select the "Full calib." parameter.
c. Enter the level value, here "3 m" (9.8 ft) for
example. Confirming the value means you assign
the pressure value present to the upper level
value.
Menu path: Setup → Extended setup → Level →
Full calib.
9Result:
The measuring range is set for 0 to 3 m (9.8 ft).
0 m corresponds to an output current of 4 mA.
3 m (9.8 ft) corresponds to an output current of 20 mA.
