Calibrate Your Module
What This Chapter Contains Use this chapter to calibrate the FLEX I/O analog modules.
In practice, you must use the I/O configuration portion of your programming
software to calibrate your modules. The software executes the methodology
explained here.
When and How to
Calibrate Your FLEX I/O
Analog I/O Module Your module is shipped already calibrated. If a calibration check is
required, the module must be in a FLEX I/O system.
Perform module calibration periodically, based on your application. Module
calibration may also be required to remove module error due to aging of
components in your system.
