Sensing Beam

The sensor uses an infrared Class 1 laser for sensing and a visible, red Class 2 laser (pilot laser) for alignment. Both lasers are aimed at

the 

identical

 target spot. The laser beams are collimated to focus on a compact spot, even at long sensing distances.

Password

The Password 

function

 provides a measure of security for the sensor 

settings.

 If Password is set to ON, the password must be entered

before the sensor is programmed. The password is 1234 and cannot be changed. Security is based on the requirement to know the

password entry procedure and the 

timeout

 

function.

 If the password is not entered within approximately 10 seconds, the sensor returns

to Run mode. Measuring 

continues

 in the background while the password is entered.

Measurement 

Selection

Select measurement in millimeters or one-hundredths of an inch. Measurements are displayed without decimal points as shown in the

Run mode display. When measuring in inches, the decimal point is two places from the right.
