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.
