Mode
Set the correction mode when performing calibration correction.
When the range is set to DI or Skip, the mode is fixed to Off.
Number of set points
Set the number of points that make up the segments (including the start and end points).

Linearizer input, Linearizer output
Enter the value of the set point. For linearizer input, set a value that is greater than the
previous value.
Selectable Range of Linearizer Input and Output Values
• Channels using linear scaling
–999999 to 999999 (the decimal place is the same as that for the scale value)
• Other channels
Values inside parentheses are examples for the 2 V range.
Linearizer approximation
Selectable range of linearizer input: Measurable range (–2.0000 to 2.0000 V)
Selectable range of linearizer output: Display range (–2.2000 to 2.2000 V)
Linearizer bias
Selectable range of linearizer input: Measurable range (–2.0000 to 2.0000 V)
Selectable range of linearizer output: Measurement span width ± 100% (–4.0000 to
4.0000 V)
