Measuring with the Cube L1

Please read chapter 12, „Important information for measuring with the Cube L1“, on 
page 26 first.

13.1 

Start measurement

Measurements with the Cube L1 should be performed exclusively with a static (motion-
less) laser beam.

1.  Observe the safety instructions in chapter 12.1 on page 26.

2.  Press the on/off button.

 The start menu appears.

 After approx. 5 seconds, the device is 

ready for operation.

3.  Turn on the laser.
• 

The measurement is started automati-
cally when the the laser is switched on.

For a high measurement accuracy, we recom-
mend an energy input of 500 J per measure-
ment (see chapter 12.2.3 on page 30).

 The thermalization is displayed by means 

of a progress bar (duration approx. 
10 seconds).  
A measuring cycle (measure, thermalize, 
send data) takes approx. 15 seconds. 
The device is then ready for a new 
measurement.
