Correction when the tank is filled
If the differential pressure lines are
equipped with shut-off and equalizing
valves, zero can be checked even when the
plant is in operation.
To achieve this, place the valve block or
equalizing valve in the test position to ob-
tain the same pressure in both measuring
chambers.
1. Close the shut-off valve in the high-
pressure line.
2. Open the equalizing valve or bypass in
the valve block.
3. Close the shut-off valve in the low-
pressure line.
The valve block is in test position!
Write protection: turn switch 4 OFF .
Press and hold down key. ZERO and
X,X mbar appear in the display.
Current signal I indicates the present
mA value.
Press key. Zero is adjusted.
Release
key, 0 mbar appears in the
display.
Current signal I = 4 mA corresponding to
the liquid level at 0 mbar differential
pressure.
(See note on gas column correction on page 17.)
Activate the write protection:
turn switch
4 ON .
Return valve block or equalizing valve to
operating position:
1. Open the shut-off valve in the low-
pressure line.
2. Close equalizing valve.
3. Open the shut-off valve in the high-
pressure line.
