LCR meters, or inductance, capacitance and resistance meters, indicate the resistance of components and sensors to a current. This is accomplished by measuring the current flowing through the unit under test, the voltage level across the unit under test, and the phase angle between the current and voltage. At this point the impedance parameters can be calculated and factored into analysis of the component. LCR meters range from handheld to benchtop units. A handheld LCR meter is lightweight, easily transportable to and from the field and battery operated. Benchtop meters allow operators to program the frequency of their meter, hone accuracy of the results to a .01% level, and interact with results on a computer.
