6.1 Mounting of the pressure connection
Pressure entries identified j and i
GB
For mounting, use an SW17 spanner to hold the connectore. (Screwing in with-
out this holding can lead to the measuring system coming loose)
6.2 To check zero point
In general the zero point is checked and set with the system not under pressure.
To correct the zero point, the measuring system fixing on the back of the case
must be loosened.
The zero point can then be readjusted by moving the measuring system to the
right or left. Once this has been done, the measuring system should be locked
again (max. tightening torque 2.5 Nm).
During the commissioning process pressure peaks must be avoided at all costs.
Open the shut-off valves slowly.
