3.4.11 CH[ ] Offset/gain temperature setting values (Un\G28 to Un\G43)

CH[ ] Offset/gain temperature setting values (Un\G28 to Un\G43)
(a) Input a value used as an offset value or gain value in 16-bit signed binary (units of
0.1 ) to the channel set in the Offset/gain setting mode (Un\G26,Un\G27).
(b) When Channel change request (YB) is turned on, measured temperature value is
compensated for the value written in this area.
All channels are set to "0".
POINT
(1) High accuracy is ensured for Offset/gain temperature setting values when the
minimum or maximum temperature of the operating range is used to
compensate errors.
(2) Set Offset/gain temperature setting values while reading measured
temperature values.
(3) Always set Offset/gain temperature setting values to satisfy the following
conditions. An error (error code: 41 ) occurs if the conditions are not
satisfied.
• Condition 1: Within the input enabled range
• Condition 2: (Gain temperature setting value) - (Offset temperature
setting value) > 0.1[
(4) Offset/gain temperature setting values are stored into the flash memory of the
Q68TD-G-H02(H01) turning on User range write request (YA), and the values
are not erased at power-off.
