PV compensation zero setting: PV (measurement value) for the remote SV input is added by the compensation value.
Setting example: Where PV of the equipment is displayed for 90°C and the actual temperature is 100°C, and the display is
to be compensated to 100°C, using the PV compensation zero setting.
The display after PV compensation is 100°C = 90°C (before PV compensation) + 10°C.

* See below for an equation for combination of the PV compensation gain setting and PV compensation zero setting.
PV of remote SV input = before PV compensation × PV compensation gain setting + PV compensation zero setting
Note
(1) Take care that stability of the measurement value may deteriorate when the PV compensation gain setting is large.
(2) Take care that the display range may change when the PV compensation gain setting is set to a multiplication factor of 1
or smaller.
Setting example: Where K thermocouple input for - 200.0 to 1372.0°C
PV compensation gain setting: Multiplied by 0.5

- 100.0 to 686.0°C
PV compensation gain setting: Multiplied by 0.1

- 20.0 to 137.2°C
(3) Take care that the display range may change when the PV compensation zero setting is set to a value other than 0.
Setting example: Where K thermocouple input for - 200 to 1372°C
PV compensation zero setting: + 100°C

- 100 to 1372°C
PV compensation zero setting: - 100°C

- 200 to 1272°C
* The display range for analog input is not affected by the PV compensation zero setting.
