Technical data subject to change

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.

■ Configurable power-up-states

■ 3 year warranty

Applications

■ Passive component trouble shooting

■ Electronic assembly

■ Quality control (component sorting)

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.
