High accuracy LCR/ESR meters were the first handheld meters of their type on the market, offering fast, reliable, and versatile testing at a low cost. With a wide range of test frequencies up to 10 kHz, these LCR meters can perform many different measurements - Z, L, C, DCR, ESR, D, Q, and diameter. These instruments are designed for both component evaluation on the production line and fundamental impedance testing for benchtop applications. With a built-in direct test fixture, you can test lead components very easily. The optional 4-wire test clip can give a convenient connection to larger components and assemblies with the accuracy of 4-wire testing. Measurement parameters: Z, L, C, DCR, ESR, D, Q, and Diameter. 0.2 percent basic accuracy. Dual LCD display. SMD Surface Mount Tweezer Probe included. Very quick response, user friendly.
