5.2 Differential pressure measurement
•FMD78: the device is ready for calibration immediately.
•PMD70 and PMD75: before calibrating the device, the impulse piping must be cleaned and
filled with fluid. → See the following table.

POS. ZERO ADJUST
Due to orientation of the device, there may be a shift in the measured value. You correct the MEASURED VALUE via
the POS. ZERO ADJUST parameter with the "Confirm" option, i. e. you assign the value 0.0 to the pressure present.
DAMPING VALUE
Enter damping time (time constant τ). The damping affects the speed at which all subsequent elements, such as the
on-site display, measured value and OUT value of the Analog Input Block react to a change in the pressure.
