the nearest distributor or branch office with a
description of the problem.
Do not execute the G.OGSTOR instruction in the
offset/gain setting mode.
• Execute the G.OGSTOR instruction only once for
one module.
• At the time of offset/gain setting, write a set value
only once at one time.
Execute the G.OGLOAD and G.OGSTOR
instructions for the same model.
Reset so that the offset value becomes smaller than
the gain value.
Set the correct value in Offset/gain setting mode and
offset/gain specification (buffer memory addresses
22, 23: Un\G22 and Un\G23).
Set a value that is within the valid range.
