This registry entry defines a tolerance value. As the ParFocal or ParCentral calibration measure the standard at each Magnification step, the results should be the same, or ‘close’, if the machine is well adjusted. If the measured results exceed this tolerance value, then the machine is considered grossly maladjusted.
Entry Name: ProbeQualVisionParCalibrationTolerance
Entry Type: Real Number to specify tolerance. The default value is 5.
