Information
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
0.2%. 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
frequencies of 100 Hz, 120 Hz, 1 KHz, 10 KHz or 100 KHz may
be selected on all applicable ranges. The test voltages of
50mVrms, 0.25 Vrms, 1 Vrmsor 1 VDC (DCR only) may also be
selected on all applicable ranges. The dual display feature
permits simultaneous measurements. When DC/AC voltage
measurement mode or the Diode/Audible Continuity Check mode
is selected, only the secondary display is used to display
the results of measurement.
The highly versatile model 889 can perform virtually all the
functions of most bench type LCR bridges. With a basic
accuracy of 0.2%, this economical LCR Meter may be
adequately substituted for a more expensive LCR bridge in
many situations. Also, with the basic accuracy of 0.4% in
voltage measurements, the model 889 performs the functions
of a general purpose Digital Voltage Meter and can be used
to replace the DVM on a service bench.
The model 889 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.
