DFG35 Digital Force Gauges
If two set points have been enabled, they are displayed in the upper left corner of the display. If only one
set point has been enabled, the word "OFF" will appear in place of the value. If no set points have been
enabled, the upper left corner of the display will be blank.
When set points are enabled, the following indicators are shown to the left of the primary reading:

9 COMMUNICATIONS AND OUTPUTS

Communication with DFG35 force gauges is achieved through the micro USB port located along the left
side of the housing, as shown in the illustration in the Power section. Communication is possible only
when the gauge is in the main operating screen (i.e. not in a menu or configuration area).
The current reading is transmitted from the gauge when the DATA key is pressed. For continuous output,
the gauge also responds to the ASCII command '?' (no quotes), terminated with a Carriage Return
character or with a Carriage Return/Line Feed combination. The gauge's responses are always
terminated with a Carriage Return/Line Feed. Any detected errors are reported back by means of error
code *10 (illegal command).
