5.4 Operation Method for the Detector
5.4.1 Zero adjustment
The zero adjustment function sets the current stylus position to the zero point for
measurement when there is a slight displacement (an error within ±90 μm/±3543.307 μin)
of the stylus on the detector.
If zero adjustment is performed, measurements and calculations are performed in the
SJ-410 with the current stylus position set to the zero point.
The allowable range of zero adjustment is within ±90 μm (±3543.307 μin). An error results
if zero adjustment is performed when the stylus is located outside of the range of ±90 μm
(±3543.307 μin). In this case, perform vertical adjustment again to position the stylus
within the range of ±90 μm (±3543.307 μin).
NOTE
• Zero adjustment cannot be performed when the measurement range is set to AUTO.
■ Operating procedure (Refer to 5.1 "■ Accessing the Drive Unit Operation screen".)
