Single-Point for Zero Only (Only Zero)
This calibration method requires no test weight, an empty scale and establishes a new zer
without affecting the conversion factor (span). This is useful to regain the full range of zer
limit when the dead load of the scale has changed. This would occur for example, if a guard
rail has been added to the scale platform. This method uses two calibration points,
6. Calibration Parameters (Swt, Zct and Sct)
The calibration parameters represent the test load weight Swt= (Span Weight) and the
analog to digital readings at zero Zct= (Zero Count) and test load Sct= (Span Count).
