Configuration
3.13
Position Trim - TP303
Via Simatic PDM
It is possible to calibrate the transmitter by means of parameters CAL_POINT_LO and
CAL_POINT_HI.
The engineering unit for the calibration is always. Using the device menu, select the calibration
menu. Then, select zero/ lower calibration menu. Apply to the input position 0.0% or the lower
position value and wait until the readout of parameter TRIMMED_VALUE stabilizes. Write 0.0 or the
lower value in the parameter CAL_POINT_LO.
Figure 3.12 - TP303 Simatic PDM - Lower Position Calibration
For each value written a calibration is performed at the desired point. This value must be inside of
the sensor range limits allowed.
Then, select upper calibration menu. Apply to the input position 100.0% or the upper position value
and wait until the readout of parameter TRIMMED_VALUE stabilizes. Write 100.0 or the upper value
in the parameter CAL_POINT_HI.

WARNING
It is recommendable, for every new calibration, to save existing trim data, by means of parameter
BACKUP_RESTORE, using option "Last Cal Backup".
