Select OUTPUT D/A CAL.
Use the up and down arrow keys to adjust the 4 mA
signal.
When increasing or decreasing the mA signal, the
increments of change increase with successive
depressions until the maximum level of change is
reached. By changing direction you will return to the
smallest increment of change. This adjustment tech-
nique speeds up the adjustment process without
affecting fine adjustment.
Use the up and down arrow keys to adjust the 20 mA
signal.
NOTE: Refer to Positioner instruction for details on
the calibrations.
