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-

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.
