SATRON VG
Measuring range
The lower and upper range-values cannot differ from zero by
more than the maximum span.
For example, range 4 transmitter whose measuring range is 0-
4/100 kPa cannot be adjusted to measure 100...104 kPa
pressure, because maximum span is
100 kPa.
Calibration stand
The calibration stand shown in Fig. 3-3 is available from the
manufacturer. The stand is equipped with coupling and
pressure connection facility. (Order number: V545728.)

3.2 Damping
If pulsation occurs in the measured pressure, it can be
damped with the damping trimmer position D under the
protective rubber shiled on the housing.

The transmitter is factory-calibrated with minimum
electrical damping.
To increase the damping, turn the trimmer clockwise.
Adjusting the damping does not affect the transmitter's
other calibration.
Damping adjustment :
1. Turn the selector switch from RUN to position D
2. Turn the regulating switch about ±20° so damping
adjustment is activated. Turn the regulating switch
to desired value of damping. 0 s on the left side, 60
s in the right side.
3. Turn the selector switch from position D to position
RUN.
3.3 Calibration examples
The calibration stand shown in Fig. 3-3 or a similar
arrangement is used to calibrate the transmitter.

Figure 3-5 Process value zero (PZ)
First step is process value zero :
1. Turn the selector switch from position RUN to
position PZ.
2. PV ZERO is done when the damping trimmer is
turned once to both edges at least for 1 sec.
3. Turn the selector switch from position PZ to position
RUN.
The maximum correction during one calibration time
is limited to 5 % of the sensor maximum range.
All the changes made using the PZ-function can be
recalled by turning the calibration trimmer to both
edges three times (reset factory settings).
