Qualimaker shows strange or unstable graph (I/U-sensor)

Possible cause:

  • Check if the voltage pick – up “tongues” are worn.
  • Check if there’s enough the “contact pressure” of those tongues or if they are bent. If they are bent; change them, do not attempt to bend them yourself, they might break!

  • Short circuit (see picture/graph beside)
    e.g. lower tongue has contact with power window!

    • check wire – usually after a short circuit the wire is damaged!

 

  • Short circuit (see picture/graph beside)
    • the wire might be damaged/broken within the Z-rail.
