5.7.2 Adjusting Conversion Curve
1. Description
 If there is certain deviation in the measurement results, you can make adjustments on the Offset value to
modify the conversion curve according to your actual needs. For example, if the deviation temperature
from the target temperature (measured temperature) is 2
°C, set the Offset of CH1 as 20 (2°C /0.1°C = 20).

 You only need to set up the PT conversion curve for once. Set up CR#40 (Set value changing prohibited)
to prevent incorrect operations.

3. Devices
 X0 = On: Set the input mode of the signals at CH1 as mode 0.
 X1 = On: Set Offset value of CH1 as 20 (2°C).
 M0 = On: Disable CH1 set value changing.
4. Program explanation
 When X0 = On, set CR#2 as K0 (H’0000) and the signal input mode at CH1 as mode 0 (J-Type).
 When X1 = On, write K20 (Offset value of CH1) into CR#28.
 When X1 goes from On to Off, set M0 = On to disable the adjustment on TC conversion curve. Write K1
(H’1) into CR#40, b0=1 to disable
CH1 set value changing.
