I use the 4-20mA current output and cannot achieve the specified accuracy.
Example at 20°C: set value 20mA, measured value 19.9772mA which gives an error of -0.114% FSR.
Such a high deviation is not expected at a constant temperature since the TUE is +/-0.15% FSR over the full temperature range!
Several configurations (internal/external reference, Rset, boost etc.) were tested without success. Schematic and measurement results are attached.
Please consider and give a hint. Thank you very much!
