Comments
This operation will cause a change in output not cor-
responding to the input. Be sure the control loop is in
manual.
Select YES.
Select D-TO-A ADJUST.
Use the arrow keys to adjust the 4 mA signal.
NOTE: When increasing or decreasing the mA sig-
nal, the increments of change increase with succes-
sive depressions until the maximum level of change
is reached. By changing direction you will return to
the smallest increment of change. This adjustment
technique speeds up the adjustment process without
affecting fine adjustment.
Use the arrow keys to adjust the 20 mA signal.
