What to try

• Start the analyzer in Service Mode:

  1. Press and hold the Power button.
  2. When the version screen appears, press and release the Mode button.
  3. Release the Power button. The analyzer starts in Service Mode — the display confirms this.
  
  Press and hold the power button. When the version screen appears, press and release the Mode button, then release the power button. The analyzer will start in Service Mode.

• Navigate to Menu > Service Mode > Sound (raw).
  Menu > Service Mode > Sound (raw)

• Observe the values displayed on the screen.
  If any value on the top two lines shows 0, this indicates that the helium sensor electronics board may be faulty.

• For diagnostic purposes, record a short video of the Sound (raw) screen and keep it available for service evaluation.

  To exit Service Mode, power the analyzer off and restart it normally by pressing the Power button.

When to contact service

If the analyzer displays a helium sensor error, produces weak clicking sounds, or shows zero values in the Sound (raw) screen, professional service is required. The electronics board may need replacement.
