Hello,
I am working on a three wheatstone bridge circuit design to acquire data from strain gauge. I am currently performing quantasization error measurement for adc and strain gauge output. But I want to know what else test I can do in order to complete characterization of the circuit? I know this is a little vague question but I would certainly like to know your suggestions.
Thanks

 

Post a circuit diagram of what you have.

 

Here is a brief explanation of the circuit diagram attached
I have LP5907, powering the analogue power supply of ADC ADS1234 and Wheatstone bridge. thus making this a ratiometric measurement. positive and negative reference of ADS1234 is connected to the positive supply of LP5907 and ground respectively. AINPx and AINNx measure the bridge output of three bridges respectively. This ads1234 is specially designed to measure differential inputs hence using them for three bridges. I have not indicated other connections of ads1234 such as SCLK, DRDY/DOUT, SPEED, GAIN0, GAIN1, XTAL1, XTAL2, A1, A0, CAP, and CAP since they are digital connections with Arduino. Currently, this whole circuit is powered by Arduino supply 5V and 3.3 V output for analogue power and digital power respectively.

I hope this is descriptive enough. thank you
