You next set Left Step to the next lower step (-1) and again measure the voltage and enter here.
Do this for all steps to calibrate the Wave or Master attenuator.
Note that is is extremely common to read the same voltage on adjacent steps. These are dummy steps inserted by the card maker (or Windows) to give the appearance of finer resolution on the sliders of the standard Windows mixer. For that reason, you should perform the calibration in Init Table mode. That way, when you set a Volts value it will be automatically entered to all softer steps, on the assumption that they are dummy steps that don't differ. As you work down from loud to soft, you will only need to enter Volts on the functional steps.
