Operation
An initial adjustment of the set point can also
be made by changing the spring tension un-
tilthedistancex(seeFig.7-1andTable7-1)
is reached.
Note that during initial set point adjustment
only a rough set point adjustment is per-
formed by turning the set point adjustment
until the distance x is reached. The special
properties of the process medium and plant
are not taken into account in this case.
Check the pressure at the pressure gauge
downstream of the regulator for a precise set
point adjustment.
