Calibrating Your Module
What This Chapter Contains
Use this chapter to calibrate the FLEX Ex analog I/O modules.
Important:This chapter provides a detailed method to perform module
calibration with individual commands. This discussion is only
given here to explain the general process.
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 Ex
Analog I/O Module
Your module is shipped to you already calibrated. If a calibration check
is required, the module must be in a FLEX Ex 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.
