5.7 Configuring Input Parameters for Linear Inputs
5.7.1 Applying a Bias to the Linear Input
When using a linear input, you can specify the bias (if any) to be applied to the input.
Applying bias allows you to compensate for any difference between sensor reading and
the point to be measured. The displayed process variable and setpoint will be offset by
the value entered here.
Parameter Name
: Input Bias (86)
Name as Displayed:
bIasbIas
Used By:
all controllers
When Displayed:
always
Range:
–1000 to 1000 (See Note 1 below.)
Default:
0
Description:
Applying bias allows you to compensate for any difference (plus
or minus) between sensor reading and the location to be
measured. The displayed process variable and setpoint will be
offset by the value entered here.
Effect on Other
Parameters:
No effect on other configuration parameters. However, the bias
will be applied to the displayed PV and the active setpoint.
Note 1: The range is reduced if a linear input is used and the value of the dSPLdSPL (display)
menu dEC.PdEC.P (decimal position) parameter is not 0 (zero). See 4.3.2 for more information
about the effect of a linear input on numerical ranges.
