Full Featured Handheld LCR Meters
B&K Precision’s 878B and 879B 40,000-count
handheld LCR meters measure inductance,
capacitance, and resistance quickly and precisely.
Additionally, the 879B supports remote control
using SCPI commands and can calculate impedance, Theta, and ESR, features typically found in
bench LCR meters only.
Fast auto ranging and quick measurement configuration such as measurement parameter and test
frequency selection make the 878B and 879B
very simple to operate. The meters also include
handy functions such as data hold,
Min/Max/Average recording, tolerance sorting,
and relative mode.
Measurement data can continuously transfer to a
PC via the meter’s mini USB interface, using
either the provided data logging software or
SCPI commands sent from a custom program.
ESR Measurements
Model 879B has the ability to measure the ESR
(Equivalent Series Resistance) of capacitors. ESR
is the sum of in-phase AC resistance of a capacitor and used to rate a capacitor’s quality. An
ideal capacitor would be lossless and have an
ESR of zero. A capacitor could measure the correct capacitance value, yet still be defective, due
to the component’s excessive in-phase AC resistance. The 879B would be able to detect this
faulty component.

Versatile Configuration
▲
Flexible Operation
A tilt stand provides position flexibility for viewing and operating the meter. The over-molding
ubber case protects the meter for better durabil-
r
ity. A single 9V battery or the included DC 12V
power adapter (with model 879B) can be used
o power the meter, giving the user options for
t
portable or bench-top use.

Faster Auto Range
The advanced auto range circuit design means
you get faster measurements without the need to
anually select ranges.

Dual Display
The 878B and 879B’s dual display allows
multiple measurements to be conveniently
displayed at once.
