D-to-A Adjust
The D-TO-A ADJUST selection is only present when you are in the
ANALOG communication mode. There are two methods available to
adjust the four to 20 milliampere output:
• Arrow key.
• Meter value entry for HART devices.
ARROW KEY ADJUSTMENT
Use this function to adjust the 4 to 20 milliampere output of the field
device using the up and down arrow keys.
Key Display 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.
Select UPDOWN ARROW KEYS.
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.
