and type the number of the first input point (if
known), or use the up and down arrow keys to scroll to the desired
analog input point.
6
Connect one end of testing leads to a calibrated voltage or current
source.
7
Connect the other end of the leads to the first analog input point on
the DC analog input termination.
8
Using the following table as a reference, adjust input voltage or
current to these levels:
•
0% of full scale
•
5% of full scale
•
95% of full scale
9
Verify that the values displayed in WESMAINT fall near the
values shown in the following table.
