Hello:
I have designed pressure transmitter based on PGA300.
With 3P1T calibration, 4-20 mA reading is always stable, but with 3P3T or 4P4T, 4-20 mA reading has 0.1% FS increasing at 8 mA, 0.2% FS increasing at 12 mA and 0.3% FS increasing at 18 mA within 30 seconds, then turn stable.
Could you please help us to eliminate those kind increasing?
Thanks!
Ed
