6.3 Resistance measurements
Bridge resistance is determined by measuring the difference between a known voltage or current
applied to the excitation (input) of a resistor bridge and the voltage measured on the output
arm. The data logger supplies a precise voltage or current excitation via U terminals. Resulting
