    I. Communication from the measuring instrument to the external display unit via cable Using this conventional configuration the data transmission between the measuring instruments (MINILEVEL NT und LEVELTRONIC NT) are connected to the external display unit (LEVELMETER 2000 or Levelmeter C25 (analogue model)) with cables II.
