Data Sheet
Model 889 Synthesized Bench In-Circuit LCR/ESR, True RMS ACV and DCV Meter with
Diode Tester
The B&K Precision Model 889 Synthesized In-Circuit LCR/ESR Meter is a high accuracy test
instrument used for measuring inductors, capacitors and resistors with a basic accuracy of
0.5%. Also, with the built-in functions of DC/AC Voltage measurements and Diode/Audible
Continuity checks, the Model 889 can not only help engineers and students to understand the
characteristic of electronics components but also being an essential tool on any service
bench.
The Model 889 is defaulted to auto ranging. However, it can be set to auto or manual ranging
by pressing the Range Hold key. When LCR measurement mode is selected, the test fre-
quencies of 100Hz, 120Hz, 1KHz 10KHz or 100KHz may be selected on all applicable
ranges. The test voltages of 50mVrms, 0.25Vrms, 1Vrms or 1VDC (DCR only) may also be
selected on all applicable ranges. The dual display feature permits simultaneous measure-
ments. When DC/AC voltage measurement mode or the Diode/Audible Continuity Check
mode is selected, only the secondary display is used.
The instrument has applications in electronic engineering labs, production facilities, service
shops, and schools. It can be used to check ESR values of capacitors, sort and/or select
components, measure unmarked and unknown components, and measure capacitance,
inductance, or resistance of cables, switches, circuit board foils, etc.
