Temperature Input Shift
Conditions of Use: The Input Type parameter must be configured as a
temperature (thermocouple or RTD) input (this excludes a non-contact
temperature sensor). The Input Shift Type parameter must be configured for
One-Point Shift.
Function: Sometimes an error may exist between the measured temperature
(PV) and the actual temperature at the control target. To offset this error, add
your configured input shift value to the input (PV). The result is displayed on
the controller as the new measurement value (PV) and used for control.
Note: The entire input range is shifted by the input shift value (1-point shift).
If the input shift value is set to –1
°C, the process is controlled to a value
obtained by subtracting 1
°C from the actual temperature (refer to
Figure 4.2).
