Hence, if a reference sensing unit, for example, is connected to {TAIL ~ the reference junction} and the exiting condition of each signal is the same as measured at the reference sensing unit, then this confirms that the entering condition of each signal transferred to the areas by the ends was likewise the same, irrespective of {HEAD ~ the probing position} used for each measurement
