axis. The re-calibration LED turns off and the value of the
re-calibration will be stored. The laser has now exited
re-calibration mode.

Note: In order to make the saved calibration effective, you must

power off the instrument after calibration, and then power it
on again. Y-axis accuracy check is a necessity after the X-axis
calibration, and X-axis accuracy check is also a necessity after
the Y-axis calibration. Laser re-calibration will not be finished
until both X-axis and Y-axis accuracy meet the specifications.

Detector Usage
1. Product Description
A laser detector is an indispensable accessory when using this rotary
