The Pulse doesn't work at my Ruida controler

Should somebody has an idea why the Pulse button doesn’t work at my Ruida controller?
I need it to calibrate my Laser.
The laser is normal working when I use it, but the button Pulse doesn’t work. The other buttons no problem.

There’s a pulse time value you can set in the controller itself. I believe it is in milliseconds, and zero means ‘continuous’. If you’ve set the value too low you might not see a pulse.

Is this the Laser Set+ ? I can’t find settings for the Puls? It stands at zero and continuous, but still no pulse off the laser.
