Product Description

The B&K Precision 889B synthesized in-circuit bench LCR/ESR meter 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/Current measurements and Diode/Audible Continuity checks, the 889B can not only help engineers and students to understand the characteristics of electronics components, but also being an essential tool on any service bench. Features:

  • Measurement parameters: Z, L, C, DCR, ESR, D, Q, ACV, DCV, ACA, DCA and Ø
  • Test conditions: 100 Hz, 120 Hz, 1 kHz, 10 kHz, 100 kHz, 200 kHz, 1 Vrms, 0.25 Vrms, 0.05 Vrms
  • 0.1% basic accuracy
  • Dual LCD display
  • Very quick response, user-friendly
  • Fully auto/manual selection
  • DC resistance measurement
  • USB interface
