  • Page 28 Commissioning Ceraphant PTP31B, PTP33B Prerequisite: This is a theoretical calibration, i.e. the pressure values for the lower and upper range are known.

  • Page 29: Performing Position Adjustment

    Ceraphant PTP31B, PTP33B Commissioning 8.4.2 Calibration with reference pressure (wet calibration = calibration with medium) Example: In this example, a device with a 400 mbar (6 psi) sensor is configured for the measuring range 0 to 300 mbar (0 to 4.4 psi).
  • Page 30 Commissioning Ceraphant PTP31B, PTP33B Prerequisite An offset is possible (parallel shifting of the sensor characteristic) to correct the orientation and any zero point drift. The set value of the parameter is subtracted from the "raw measured value". The requirement to be able to perform a zero point shift without changing the span is met with the offset function.
  • Page 31 Ceraphant PTP31B, PTP33B Commissioning Example 1 • Measured value = 2.2 mbar (0.033 psi) • You use the "GTZ" parameter to correct the measured value with the value, e.g. 2.2 mbar (0.033 psi). This means that you are assigning the value 0 mbar (0 psi) to the pressure present.
