Laser spot is not at the center of "Recognition Circle"

If the laser spot is not in the center of the "Recognition Circle", which is the center of the cross in the magnifier, it will cause the inaccurate measurement.

Cure:
Manually move the laser spot to the center of the cross-hair.

1. Touch and hold on the recognition circle for 2 seconds till the magnifier pops up.
2. On the magnifier, move the laser spot to the center of the cross-hair.
3. Tap "Measure" to recalculate the distance, length or width.

Note:
Whenever you see the laser spot is not in the center, either in calibration process or in measurement, please always correct it manually.
