  • Page 20: Connecting Wire Setting

    DT1310 xx xx 7.2. Connecting wire setting Function The Pt / resistance / potentiometer can be connected to the input either with 4 / 3 / 2 wire. The 4 wire connection gives the best result: the instrument is able to compensate the connecting cable resistances. The 3 wire mode is a compromise it may give a good result when all the 3 wire have same resistance.

  • Page 21: Input Mode Setting

    DT1310 xx xx 7.3.
