7.5 Precautions for Online Module Change
The following are the precautions for online module change.
(1) Always perform an online module change in the correct procedure. A failure to do
so can cause a malfunction or failure.
(2) If an online module change is made with the user range setting, the accuracy
after that will fall to about less than three times of the accuracy before that.
Re-set the offset/gain values as necessary.
