Sample probe fails to go down

Under normal circumstances, the sample probe goes down.
If sample probe fails to go down check the following:

• Sample probe depth wrong. Check the correct sample depth: Settings - General settings - Sample probe depth
  • If the sample probe has being set too deep, it will touch the bottom of the sample tube. The sample probe then pushes the sample tube slightly downwards, and the aspiration cycle will be aborted.
  • A broken outer needle may cause a similar fault.
• Check for mechanical obstructions.
• Electronic failure.
  • Fatal error, call distributor.
