Hello Drpat.
As Wntrmute stated, the calibration manual is availble in PDF format on VPI's website. The calibration of selecting the "ramp down" voltage is all done via the push buttons on the SDS's front faceplate.
And there's also an hour meter available, you can actually know how many hours of use been placed on your unit.
With my own HW-19 (16lb MK-IV Platter), which had the 600rpm stock Motor, and I'd power up via the Table's on-off switch located on the base, or when I got the VPI SAMA for the HW-19, and decided to power the Table direct from the SDS's switch, never had a problem either way.
More than likely, it would be a problem with the run capacitor on board. Although there just might be that possibility as well, with an ultra heavy platter like the Super Platter, one might have to help it along.
This is something I always commonly do with my own table, as it helps reduce wear and tear on the drive belt. Mark
