When factory default settings are used, offset/gain setting is not required.
If the utility package is installed, set offset/gain setting values according to the procedure
described in Section 5.6.2.
(1) Setting procedure
Identify the disconnected
channel with the
Disconnection detection flag
(Un\G49), review the wiring
of the corresponding
channel, and turn YF from
ON to OFF.

Input a value used as a gain value to the
adjusting target channel using a RTD or
standard resistor.
Check that the "RUN" LED is flashing to indicate
the offset/gain setting mode.
Switch to the offset/gain setting mode.

Confirm that the Channel change completion flag
(XB) has turned ON.
Set the gain setting channel in the Offset/gain
setting mode (Gain specification) (Un\G27) and set
"0" in the Offset/gain setting mode (Offset
specification) (Un\G26).
Confirm that the Offset/gain setting mode status flag
(XA) has turned OFF.
