Offset/Gain Setting
Set offset/gain setting values in the following procedure.
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.
YES
NO

2)
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.
*1
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.
Write the measurement setting value equivalent to 
the input to the CH     Gain temperature setting 
value (Un\G29)

 of the adjusting target channel.
Set the offset setting channel in the Offset/gain 
setting mode (Offset specification) (Un\G26) and 
set "0" in the Offset/gain setting mode (Gain 
specification) (Un\G27).
Set "Enable" for the Conversion enable/disable 
setting (Un\G0) of the offset/gain setting target 
channel and turn Y9 from ON to OFF.

With the intelligent function module switch 
setting, set the RTD type to be used and the 
temperature range for the measurement range 
setting of a channel targeted for adjusting 
offset/gain values.
Confirm that the Channel change completion 
flag (XB) has turned ON.
Input a value used as an offset value to the 
adjusting target channel using a RTD or 
standard resistor.
Turn OFF Channel change request (YB).
