Measurement with pulsed lasers

Limited measurement with pulsed lasers is possible. When it comes to pulsed laser 
radiation a correct exposure time measurement up to a pulse frequency of 1 kHz and a 
duty cycle of 50 % is possible. 
In case of on/off times shorter than 500 μs a correct exposure time measurement is not 
possible.

11.6 

Reading off measuring values

The last 14 measuring values can be read off from the display of The Cube. You can 
read off the last 30 measuring values with the optional Android™ PRIMES Cube App for 
mobile devices or optional LaserDiagnosticsSoftware LDS.

 

X

Press the on/off button for approx. 
2 seconds.

  The measured values and the time are 

displayed. 

 

X

Press the on/off button again for 2 se-
conds to have the remaining measuring 
values (no. 8-14) displayed.
