  • Power supply with rechargeable battery pack 4.8V/1.500 mAh NIMH
  • Error detection in 3 steps: without closure, with one closure and with two closure
  • Short-circuit display A-B core with distance reading in meters
  • Short-circuit display A-B shield with distance reading in meters
  • Line and shield break display with distance reading in meters
  • Display for interchanged signal lines A-B
  • Display for incorrect or missing bus closures
  • Display for incorrect position of the bus connectors
  • Error due to inadmissible line length
  • Error in characteristic impedance
  • Incorrectly used cable type
  • Reflections
  • Error in sending and reception levels
  • Error due to use of inadmissible branch lines
