Additionally, the 879B can calculate impedance, Theta, and ESR, features typically found in bench LCR meters only. 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. 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.

The over-molding rubber case protects the meter for better durability. A single 9V battery or the included DC 12V power adapter (with model 879B) can be used to power the meter, giving the user options for portable or bench-top use. The advanced auto range circuit design means you get faster measurements without the need to manually select ranges.
