Note:

LED Inspection Function
• The function operates correctly, provided that the position of the measuring

head remains the same before, while, and after the intensity of light is
checked. The intensity of light fluctuates if the mounting position shifts.

• This function cannot be used to check errors in the mounting position of the

measuring head.

• This function is not intended to guarantee the measurement accuracy of the

LS-7600 Series. Use master workpieces such as pin gauges to check the
measurement accuracy.

• The intensity of light displayed will decrease by approximately 6% if the

mutual interference prevention function is used. Furthermore, the intensity of
light displayed will decrease by approximately 11% if the cable between the
controller and measuring head is extended to 40 m. They are not errors.
Check the intensity of LED light source based on the displayed value.
