6.4.2.8 HART trimmer calibration
When the HART transmitter needs to be recalibrated or adjusted the HART menu can achieve
these two types of possibilities:
- ADJ.SCL
- CAL.TRIM
CAL.TRIM permits to correct the analog mA generation, of the HART transmitter, referred to the
digital AO value displayed if the output DAC goes out of tolerance.
Zero and Span needs to be corrected.
If the user wants to recalibrate the Trim. an INPUT mA measurement channel has to configured as
REF channel. In addition, the loop wiring needs to flow to the IN mA terminals.
If no REF mA Input channel is configured first an error will be shown.
