CH1 Offset temperature setting value
As Channel change request (YB) is turned on and off in offset/gain setting mode, the measured temperature value is
corrected by a value written in this area.
Specify the value of a 16-bit signed binary number.
■Buffer memory address
The following shows the buffer memory address of this area.

Setting a value out of the range causes an offset/gain temperature setting value range error (error code: 1ECH).
'CH1 Offset temperature setting value' (Un\G562) and 'CH1 Gain temperature setting value' (Un\G564) must be set to be
within the following temperature input range:
• Gain temperature set value - Offset temperature set value > 0.1
A channel where the set value is out of the above range causes an offset/gain temperature setting error (error code: 1E9H).
■Default value
The default value is 0 for all the channels.
• An effective way to achieve high accuracy is to set up error correction in 'CH1 Offset temperature setting
value' (Un\G562) and 'CH1 Gain temperature setting value' (Un\G564) assuming the minimum and
maximum temperatures of the used range.
• Configure 'CH1 Offset temperature setting value' (Un\G562) and 'CH1 Gain temperature setting value'
(Un\G564) while reading out measured temperature values.
