To whom may it concern,
To operate PGA309A in 3-wire mode, we connect Vout to PRG and ONE to PRG respectively.
and connect external Rt- (pt100) RTD, as attached picture. I want to calibrate 3-points(-10 / 25 / 80 degrees).
Pls let me know(ppt file for calibration, and pre-cal file), refer to belows.
- PGA309 in 3 wire mode.
- Rt-, pt100 RTD external temperature sensor.
- Vout max and Vout min are 5V and 1V.
- Calibrate Nonlineraty.

- No use Sensor Emulator (use real world sensor).
- use USB DAQ and PGA309EVM-USB program.
Look forward to your reply.
