Installed a momentary push button for laser fire test. Laser is at full power

I installed a momentary push button for test firing the laser. But the amp meter jumped way too high. I installed it on the Laser power supply G and L pins. I also installed the potentionometer from Cohesion on the G In 5V pins of the Laser Power Supply and it does not seem to adjust the power at all. I used the Support Documentation but something is not working write.

Working now. Even thow the poteniometer I bought from Cohesion showed to be the same as in the documentation, I had to reverse 2 wires and now the test fire is working good.
