878B Datasheet, PDF (1/8 Pages) List of Unclassifed Manufacturers – 40,000 counts resolution on primary and 10,000 counts resolution on secondary display

Data Sheet
40,000-Count Dual-Display Handheld LCR Meters
Models 878B, 879B, and 880
Full Featured Handheld LCR Meters
The 878B, 879B, and 880 40,000-count
handheld LCR meters measure inductance,
capacitance, and resistance quickly and precisely.
The 879B and 880 also measure impedance,
Theta, and ESR. Additionally, the 880 offers
capabilities typically only found in bench LCR
meters such as a 4-terminal configuration, basic
measurement accuracy up to 0.1 %, test
frequencies up to 100 kHz, selectable test signal
levels and measurement rate.
Fast auto ranging and quick measurement
configuration such as measurement parameter
and test frequency selection make these meters
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
Models 879B and 880 have 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 and
880 would be able to detect this faulty
component.
