numberLCRThe bridge is based on the principle of AC impedance measurement, and the workflow is as follows:

Signal excitation: The instrument is equipped with a high-precision sine wave signal source, which applies a fixed frequency and amplitude AC voltage to the measured components (such as capacitors and inductors)/electric current.

Impedance sampling: Using an internal high-precision current and voltage sampling circuit, synchronously collect the voltage signal and current signal flowing through the tested component, and calculate the amplitude and phase difference of the impedance.

Parameter conversion: Based on the amplitude, phase difference, and excitation signal frequency of the impedance, the inductance is automatically converted using a built-in algorithm（L）Capacitor（C）Resistance（R）Value, while calculating the loss factor (such as capacitance)DValue and inductanceQValue).

Features:

High precision measurement:numberLCRbridgeCapable of providing high-precision measurement results, with basic measurement accuracy up to0.3%Even higher.

Multi functional measurement: In addition to measuring inductance, capacitance, and resistance, it can also measure quality factor（QValue, loss factor（DDerived parameters such as value, impedance phase angle, etc.

Multi frequency testing: Supports multiple testing frequencies, and users can choose the appropriate testing frequency based on component characteristics.

Equivalent circuit model: supports series connection/Parallel equivalent circuit model, suitable for testing requirements of different components. For example, small capacitors are commonly modeled in parallel, while large inductors are modeled in series.

Automated operation: It has functions such as automatic range switching, fast display of results, supports calibration function, and improves measurement efficiency.

Convenient data processing: equipped withLCDScreen, data storagePCInterface and other functions facilitate data analysis and management.
