6.
If the distance to the remote sensor is more than 8 inches, the use of twisted pair cable is recommended. It will work up to
around 6 to 12 feet.
7.
Because the measurement technique uses switched current sources, excessive cable and/or filter capacitance will affect the
measurement accuracy. When using long cables, the filter capacitor may be reduced or removed. Cable resistance can also
induce errors. 1
Ω
series resistance introduces about 0.5
