Configuration
3.3
It is possible to calibrate the transmitter by means of parameters CAL_POINT_LO and CAL-POINT-
HI.
Let’s take the lower value as an example: write 4 mA or the lower value in parameter
CAL_POINT_LO.
Figure 3.2 - Calibrating the Cal Point Lo – FI302
Always keep in mind that, simply by writing in this parameter, the trim procedure is initialized.
Read the current in the multimeter and write that value in parameter FEEDBACK_CAL. Write in this
parameter until it reads 4.0 mA or the lower value readout of the multimeter.

This parameter
indicates where the
converter should be
when the setpoint lower
value is 0%. The desired value
should be entered.
This parameter should
be set with the actual
output current during the
calibration procedure. The value should be
entered here.
