Operation overview of precision lcr tester

Precision lcr tester is generally used to test inductance and capacitance. The measurement steps are as follows: 1. Set test frequency 2. Test voltage or current level 3. Select test parameters such as z, q, ls (series inductance), lp (parallel inductance), cs (series inductance), cp (parallel capacitance) , D, etc. 4. Instrument calibration, calibration is mainly for open circuit and short circuit calibration, high-end instruments need to perform load calibration 5. Select test fixture 6. Fixture compensation 7. Put dut on the fixture to start the test
