Use the following procedures to calibrate the analog inputs after replacing
the optional I/O expansion board. These procedures include selecting
analog input channels, calibrating them to zero volts, and then calibrating
them to full scale using a known voltage source.
Use the following procedure to calibrate the input channels to zero volts.
1. From the Main Menu, press
to scroll to Analog Input Calibration, and press
The Analog Input Cal screen displays.
