Calibration Note
: Typically analog instrument calibration is done at the "top" (usually the right hand) of each scale. Intermediate calibration markings are "checked" but may or may not be accurate. The reason for this is the OEM calibrated each meter face individually for that particular SN instrument. Over time, the original tubes have been replaced, other components have been replaced, meter movements have been replaced, so the chances of the unit "calibration" being accurate at all portions of the scale of a particular instrument, are close to zero.
