Self-calibration function is provided to ensure the

precision of the device.

The adjustment range is -9~9mm. Finally, long press

to save the setting.

After the adjustment, press to save the

calibration result .

For example, the actual distance is 3.780m.

If the measured value is 3.778m, 2mm smaller than

the actual value, the calibration value can be

adjusted up by 2mm on the existing basis with

through the calibration function.

If the measured value is 3.783m, 3mm larger than

the actual value, the calibration value can be

lowered by 3mm on the existing basis with

through the calibration function.
