4 Carry out a position correction if the following conditions apply. If
the conditions are not fulfilled, then carry out the position
correction after step 6.
Conditions:
The process cannot be sealed off.
The pressure extraction points (A and B) are at the same geodesic
height.
5 Put measurement loop into operation:
Close valve 3: Separate plus and minus side
Open valve 4: Connect minus side
Now:
Valves 1, 3, 5, 6 and 7 are closed 4)
Valves 2 and 4 open
Valves A and B open (if available)
6 Carry out position correction, if flow can be blocked. In this case,
step 5 is deleted.
Then carry out adjustment, see chapter "Set parameters".
8 .3 Level measurement
For level measurements, the DPT10 in all versions is used.
DPT 10 with bilateral isolating diaphragm CSB is immediately ready for
operation.
The DPT10 without isolating diaphragm or with unilaterial isolating
diaphragm CSS is ready for operation after opening a possibly
available block valve.
Before you adjust DPT10 without isolating diaphragm or with unilateral
isolating diaphragm, the effective pressure lines must be cleaned and
the instrument filled with the medium.
4) Valves 1, 3, 5: Configuration with 5 valves.
