... 3.5. User Re-zero Over time it is possible that the input may ‘drift’ slightly due to various conditions (temperature changes, etc.). As such it may be necessary for the channel to be re-zeroed by the user. The user re-zero function is provided for this task. It simply takes the current reading (sam ...
