There is no specific length limit for the sensing cable, but it is recommended to use twisted pair or shielded cables to minimize noise in the high impedance circuit.
The user’s manual states that connection should be made as short as possible.
Since the compensation voltage of the sensing cable is 1.5 V, it is recommended to use a cable rated for 1.5 V or less. The recommended cable length is approx. 5 m, so the recommended length for the sensing cable is also 5 m.
