1 Control stability of the electronics only, in ideal thermal system
2 Current source error has negligible effect on measurement accuracy
3 Diode input excitation can be set to 1 mA
4 Current source error is removed during calibration
5 Accuracy specification does not include errors from room temperature compensation
