Please do as follow:
- Connect the laser module, connect the power supply to the laser test board, The voltage of the laser module is equal to the input power supply voltage.
- Access laser module
- Press the ℃ button
- Press the switch key to switch to test mode, and 001 should be displayed at this time
- Press the PWM + key continuously until 100%
Normally:
In step 1, connect the power supply to the laser test board, and the test board should display the “off” sign. In step 2, after connecting the laser module, the last point of the digital display should flash. In step 3, press the ℃ button to display the module temperature. In step 4, the nixie tube should display 001. At this time, “test mode” should be on instead of “TTL in” led. At this time, The laser should be a very low power output. In step 5, the laser intensity will gradually increase until 100%
