The 5112 does not have a readable temperature device.  The specification recommends self-calibrating if the ambient temperature changes by more than 2 degrees C because within +/- 2 degrees C of the self-calibrated temperature is where we guarantee our specs.  Once the board drifts beyond 2 degrees C from the self-calibrated temperature, gain and offset drift can affect your measurements.  Please let me know if you have further questions.
