B&K Precision’s 878B and 879B 40,000-count
handheld LCR meters measure inductance,
capacitance, and resistance quickly and precisely.
Additionally, the 879B can calculate impedance,
Theta, and ESR, features typically found in bench
LCR meters only.
Fast auto ranging and quick measurement config-
uration 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.

Full Featured Handheld LCR Meters
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 capaci-
tor 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 cor-
rect capacitance value, yet still be defective, due
to the component’s excessive in-phase AC resist-
ance. The 879B would be able to detect this
faulty component.
