Setting of PV shift
(1) PV shift function
• It is possible to arithmetically operate the measured value and to record the display the result.
• Set the inclination and shift value for PV shift arithmetic operation.
The conversion graphs after execution of shift arithmetic operation and inclination arithmetic opera-
tion are indicated below.

arithmetic operation
• PV shift arithmetic operation is of the following expression.
P' = AP + B
where; P': Measured value after PV shift arithmetic operation
P: Measured value
A: Gain (0.01 to 327.67%)
B: Shift value (-32767 to 32767 engineering value; decimal point varies by input type)
• The measured value after PV shift arithmetic operation is limited so that it is located
within the recording range settable range of the input type set for each channel.
• When the input type is changed or when ON/OFF of the scaling function is made, the PV shift set
value of the subject channel is cleared.
• The PV shift set value is not copied even when the set value is copied by making use of the setup
copy function.
