Compensation
only with Pt100 / Pt1000: Select "3-wire" or choose a total wire
resistance for 2-wires.
2-wire technique wire resistance compensation:
To compensate the wire resistance short-circuit the wires nearby the
sensor and measure the wire resistance. We recommend to use 2 or
better 3 wires for each sensor.
With 2-wire connection and a common wire for all signals, all sensor
measuring currents will be added on the common wire. Thus the value
of the compensation wire resistance RK must be calculated as follows:
RK = (n+1) x RL/2
(RL = wire resistance of two wires, n = number of sensors)
