Screen / Data Zero Units

Controls: Zero Dialog >> Units
Macro: ZeroUnits

The Units button in the Zero control dialog toggles both Screen Zero and Data Zero Manual units. The default is percent of full-scale. When the button is depressed, the units change to volts (or arbitrary User Units, if active).

Note that channels must be calibrated in order for volts or User Units to read correctly.


Macro Notes:

ZeroUnits=0 sets the Zero dialog Units to percent (%).

ZeroUnits=1 sets the Zero dialog Units to volts (or to User Units, if active).

Note that attempts to use this command when it is disabled in Spectrum, Spectrogram, or Pitch Track modes will result in "Control disabled. Aborting macro."
