Wiring 3-wire strain gauges in full bridge configuration

[cwilltr]

Hello,

I am wondering how 3 wire strain gauges are supposed to be wired in a full bridge configuration? There is some information out on the internet for wiring a 3 wire strain gauges in a quarter bridge setup, but nothing for a full-bridge.

I have been able to get voltage readings with just using 2 of the 3 wires in a full bridge-setup (leaving one floating wire) and was able to get a change in voltage that is linear with elongation. I used these voltage and elongation points to create a line.

However, the voltages will change throughout the day (possibly because of temperature?) and the voltage output will no longer match the line that I created earlier. 

Thank you
