Data Zero Manual Adjust
When Data Zero Manual mode is active, the Adjust controls allow you to set any arbitrary value as the effective zero position for waveform data.
Usually, you will want to use the adjacent Null controls to automatically set the Adjust value to the current average input value (after first applying an effective zero condition). But a manual adjustment can be handy for special circumstances, and is especially useful for "what if" studies of Histogram and PSTH averages.
LI.ZeroAdj=10 sets the Left Input channel Manual Adjust value to 10% of the full-scale range, assuming the Zero Units button is off.
If Units is active, this same command attempt to set to 10 volts (or 10 User Units), limiting the value to the actual full-scale range as needed. You can use LI.ZeroAdj=10m to set 10 mV (or 10 milli-units for User Units).
Similarly, RI.ZeroAdj sets the Right Input, LO.ZeroAdj sets the Left Output, and RO.ZeroAdj sets the Right Output.
Alternatively, you can use the Ch. prefix to set a channel previously specified via the Ch Channel Select command.
Note that attempts to use these commands when the controls are disabled in Spectrum, Spectrogram, or Pitch Track modes will result in "Control disabled. Aborting macro."
