The BK Precision Model 889B synthesized in-circuit LCR/ESR Meter with Component Tester is a high accuracy test instrument used for measuring inductors, capacitors and resistors with a basic accuracy of 0.1%. Also, with the built-in functions of DC/AC Voltage measurements and Diode/Audible Continuity checks, the Model 889B can not only help engineers and students to understand the characteristics of electronic components but also being an essential tool on any service bench.
