- Digital Laser Sensor LV-N10 Series User's Manual -

This sensitivity setting method is useful if the received light intensity is reduced by

dust or dirt.

The setting value is calibrated to be slightly than the light intensity received when it is

determined.

When a workpiece is absent for the

reflective model, or when a workpiece

is present for the thrubeam model/

retro-reflective model, press and hold

the [SET] button for 3 seconds or

more.

Release the button when "SEt" flashes.

Calibration is complete after the setting

value flashes momentarily, and then stops

(lights up).

Press the button to adjust the setting

value.

When performing two-point calibration on channel 2 of the 2-output type,

set the channel switch to "2".

able if the background is more reflective than the workpiece.
