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℃error.
