A 20-breakpoint (custom) linearizer. Custom linearizers are applied by:
1. Selecting an analog source as the input to the linearizer.
2. Selecting the custom linearizer output as the source to be displayed.
The engineering range and units of the input source are assigned to the custom
linearizer output.
Selects the input source to be linearized – see page Appendix A, page 116 for description of
sources.
Set X and Y values as a % of the engineering range input source.
Selects the breakpoint to be configured.
X is input to the linearizer expressed as a % of the electrical range.
Y is output expressed as a % of the engineering range.
Once configured, a custom linearizer must be soft-wired to an input or output using the custom
template feature – see Section 7.1, page 36.
