Figure 3.12 – IF303 Simatic PDM Lower Current Calibration.
Let’s take the upper value as an example:
Supply 20 mA or the upper value to the terminal block and wait until the readout of parameter
PRIMARY_VALUE stabilizes.
Write 20.00 or the upper value in parameter CAL_POINT_HI. For each value written a calibration is
performed at the desired point.

WARNING
It is recommendable, for every new calibration, to save existing trim data by means of parameter
BACKUP_RESTORE, using option "Last Cal Backup".
Via Local Adjustment
The
IF303
has 3 input transducers and its device leaves SMAR with factory settings. The factory
setting establishes only the transducers #1 as default for local adjustment. In order to configure the
others via local adjustment, the user should configure them in the display transducer via
Configuration Tool, according specific instructions for this transducer block.
