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

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.

DPT10 with bilateral isolating diaphragm CSB is immediately ready for

operation.

The DPT 10 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.

Valves 1, 3, 5: Conﬁguration with 5 valves.
