(2) Reference table for user range settings offset/gain values (buffer memory
addresses 218 to 233: Un\G218 to 233)
Example: When the offset value and gain value of channel 1 are 1V and 5V,
respectively, in the Q68DAV, the reference value of the CH1 user
range settings offset value (buffer memory address 218: Un\G218) is
approx. 8CB4
(buffer memory address 220: Un\G220) is approx. BFAE

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.
