Configuring the CX1000/CX2000
Reference Deviation
Turn the reference deviation ON or OFF, and specify the value from 1 digit of the
measurement span to EUS (100.0%). With style number S1 (system setting), it is not
displayed if the PID number is 1. With style 2 or later, it is not displayed when the PID
number is 2 or less.
Linearize (When PV/SP Computation Is OFF)
Mode
Select the linearize mode from [OFF], [Biasing], or [Approximation].
Input
Enter the linearize input value. (The value depends on the linearize mode.)
Biasing: Set with EU (-5.0 to 105.0%) of the measurement input span.
Approximation: Set with EU (-5.0 to 105.0%) of the measurement input span.
Set between 2 and 11 points.
Output
Enter the linearize output value. (The value depends on the linearize mode.)
Biasing: Set with EUS (-100.0 to 100.0%) of the measurement input span.
Approximation: Set with EU (-5.0 to 105.0%) of the measurement input span.
Note
• With linearize bias, set so that input + output is EU(0-100%). Also, set so that linearizer input
+ linearizer output is greater than or equal to the previous linearizer input + linearizer output.
• Set so that linearizer approximation output is more than the previous value.
• Starting from the third point, if you set a value smaller than the previous value, all settings
after that point become disabled.
• When the PV/SP computation function is ON, the above settings are entered for each
control input channel item under Control Input Channel on the Setting tab. See page 7-30
for the setting method.
