Troubleshooting

1) General

1. Restart the connected devices and then the program
2. Check the log file, which might contain helpful information. It is located in the cache directory, usually in ~/.cache/cpdctrl-gui.
3. Ask superuser

2) The Arduino/LEDD1B does not work

1. Make sure the Thorlabs LED is plugged in, turned on (turn the dial to a non-zero value) and that the switch is in the TRIGer position
2. Reset the Arduino by pressing the white button on the top and restart the program
3. Unplug and replug the Arduino and restart the program
4. Re-upload the code (see section "Technical Information/Arduino Code")

3) Pressure does not drop enough

Usual values:

• Before turbo tump:
  • 1E-3: ~5 minutes
  • 2E-2: ~25 minutes
• With turbo tump:
  • 1E-4: TODO
  • 1E-5: TODO
  • 1E-6: after 1-2 days

1. Make sure the housing sits properly on the baseplate, and no cable is sticking out (check the backside!)
2. Inspect for leaks using isopropanol
3. Perhaps the grease has to be re-applied, ask superuser
