Patent ID: 8917102

Claim:
A method for measuring a capacitance using a capacitance meter, the capacitance meter comprising an AC power source with a controllable frequency which is fed to a capacitor to measure a capacitance of the capacitor, the method comprising: performing, in the capacitance meter, a first measurement of the capacitance using a first frequency; when the first measurement of the capacitance indicates the capacitance is below a threshold capacitance, performing a lower capacitance measurement in the capacitance meter, using a second measurement of the capacitance using a second frequency; and when the first measurement of the capacitance indicates the capacitance is above a threshold capacitance, performing a higher capacitance measurement in the capacitance meter, using a second measurement of the capacitance using a third frequency, the third frequency being lower than the second frequency, wherein the performing the lower capacitance measurement involves using the second frequency and a fourth frequency, wherein the second and fourth frequencies differ, and wherein the performing the higher capacitance measurement involves using the third frequency and a fifth frequency, wherein the third and fifth frequencies differ.
