9.4 Wire line adjustment
To compensate the line resistance short circuit the wires nearby the sensor, measure resistance and enter
this value for line resistance. With 2-wire connection and a common line for all signals, all sensor measuring
currents will be added on the common line. Thus the value of the compensation line resistance RK must be
calculated as follows:
RK = (n+1) x RL/2 (RL = resistance of two wires, n = number of sensors)
