Communication problem with Thorlabs PM100USB Power meter

[Ayushya]

I have a LabView Instrument in which I use the Thorlabs PM100USB Power meter. (VI attached). During measurement, the programm suddenly stops measuring and stops responding, then starts and stops arbitrarily instead of measuring continuously (screenshot). What could be done in this case?

Hi Ayusha,

what about implementing some error handling?

What about implementing a loop in your VI instead of using the "run continuous" button?

What about not calling Init/Deinit with each iteration your your VI (or the future loop)?

Try adding a for or while loop. Keep the ThorLabs open and close functions outside of the loop.

Thanks GerdW. I followed your points and was able to solve my problem.

Thanks Kevin. I tried with adding a while loop and also kept the getWavelength part outside the loop. It works.
