Auto-Tune: Initiates auto-tune for Output 1. This parameter appears if Ot 1 =ht.
Range: 0 = off, 1 = slow, 2 = medium, 3 = fast Default: 0
Local-Remote: Selects a local or remote set point for the Series 945. This parameter
only appears if the LOC parameter = 0, 1 or 2, and rSP = 0-5 or 420. If L-r = r, the
remote set point will be displayed in place of the internal set point.
Range: L = Local operation r = remote operation Default: L
