Calibration
The PID module is calibrated before it leaves the factory. The calibration
of the module should be checked yearly. It can be returned to
Allen-Bradley Systems Division for factory calibration. Revision B and
later models can be calibrated using the procedures described in this
chapter.
The following test equipment and parts should be available. Some of this
equipment can be borrowed from the system installation or an
independent test station can be used.
