3.4.7 Offset/gain setting mode and offset/gain specification
(buffer memory addresses 22, 23: Un\G22, Un\G23)
(1) Specifies the channel to be adjusted for the offset/gain settings.
(2) The channel change request (YB) must be turned ON/OFF to validate the
offset/gain setting offset specification or gain specification. (Refer to Section
3.3.2.)
(3) Specification can be made for 1 channel only.
If setting is made for two or more channels simultaneously, an error occurs and
the corresponding error code (buffer memory address 19: Un\G19) is stored.
(4) See Section 4.6 for the details of the offset/gain settings.

3.4.8 Offset/gain adjustment value specification (buffer memory address 24: Un\G24)
(1) This area is used to set the amount of adjustment for analog output values in the
offset/gain setting mode.
(2) Turning the set value change request (YC) from OFF to ON increments or
decrements the analog output value by the adjustment value.
(3) The valid input range is from –3000 to 3000.
When the input value is 1000, the analog output values can be adjusted by about
0.33 V (user range setting2) and about 0.18 V (user range setting3) for voltage
output and about 0.67 mA for current output.
(4) See Section 4.6 for the details of the offset/gain settings.
