Output To line, then press
to save the value.
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, choose Service >
Analog Input Cal
.
The Analog Input Cal screen appears.
Note
If Service Mode is not displayed, refer to “
