PT100test

Hi ZFJC ,

Can you share your schematic for this? 

Have you also checked the reference design for RTD measurement system using AD7124? If not you may refer to the link below:

CN0383 Circuit Note | Analog Devices

CN-0383 (Rev.D) (analog.com)

The reference designs are engineered and tested for quick and easy system integration to help solve today’s analog, mixed-signal, and RF design challenges. This circuit note provided above uses a Class B Pt100 RTD sensor with an accuracy of ±0.3°C at 0°C but it can support other classes such as Class A, Class AA, 1/3 DIN, or 1/10 DIN that are higher accuracy RTDs. You may refer to the circuit note for better understanding on how to setup your PT100 using AD7124.
