Capacitors are the energy reservoirs that supply bursts of power to maintain consistent operation during transient demands. To accurately measure capacitors, we use capacitance meters. In this article, understand where capacitance meters are used, what their capabilities are, and how they're used to measure components and diagnose problems.
However, when a project demands the highest quality standards, benchtop capacitance meters and LCR meters offer much better accuracy. The recommended technique to accurately measure the capacitance using benchtop meters involves four test leads instead of two: The two current test leads measure the current flow across the device under test (DUT).
Using the calculated losses, the software computes the capacitance or inductance at one of the two frequencies (effective frequency). The effective test signal is included as a reference. It is the signal that yields a comparable capacitance or inductance value if measured with the single-tone measurement technique.
Unlike a capacitance meter, a digital multimeter typically measures the capacitance only under a constant DC signal and can't measure parasitic elements like ESRs. That's why capacitance meters are essential capacitance measurement devices that belong on every test engineer's desk. How do capacitance meters compare with LCR meters?
The recommended technique to accurately measure the capacitance using benchtop meters involves four test leads instead of two: The two current test leads measure the current flow across the device under test (DUT). This is the current that's able to flow under the net impedance of the DUT, which includes the ESR, ESL, and EPR.
Handheld capacitance meters are great instruments for most day-to-day testing and verification work. However, when a project demands the highest quality standards, benchtop capacitance meters and LCR meters offer much better accuracy.
