The 878B and 879B 40,000-count handheld LCR meters measures 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 configuration such as measurement parameter and test frequency selection make the 878B and 879B very simple to operate. The meters also includes 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 mini USB interface, using either the provided data logging software or SCPI commands sent from a custom program.
