4. On the remote, press the

buttons to move the laser line

up and/or down, until the laser line hits directly on reference
point ‘0’.

Accuracy Calibration of the Z-Axis:
Place the instrument horizontally, and enter the self-calibration using

the same method as for the X and Y-axis calibration. Adjust the
projected laser point to make it coincide with point ‘0’.

Calibration Confirm:
Press the button to confirm the calibration value after calibration

is completed. Instrument will return to normal operation mode.

Note: In the self-check and calibration mode, self-calibration

coefficient is from 1600-2495. If user calibrates in this range,
and accuracy is still not achievable, please contact an authorized
service center or dealer for repair.

• After calibration is complete, user must turn the instrument

off and then back on. Calibration is then complete.

• When calibrating, the user must check accuracy of both the

X and Y-axis, until both are within accuracy specification.
