B&K Precision 879B – Deluxe Universal LCR Meter

• L, C, R, and Z primary measurements
• Automatic calculation of secondary parameters D, Q, Theta, ESR
• Backlit display
• Fast auto range design for rapid, easy component measurements
• Relative mode
• Visible and audible tolerance mode

The model 879B 40,000-count handheld LCR meter measures inductance, capacitance, and resistance quickly and precisely. Additionally, the 879B supports remote control using SCPI commands and can calculate impedance, T, and ESR features typically found only in bench LCR meters. Fast auto-ranging and quick measurement configuration such as measurement parameters and test frequency selection make the 879B very simple to operate. The meter 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’s mini USB interface, using either the provided data logging software or SCPI commands sent from a custom program.

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.

Flexible Operation

A tilt stand provides position flexibility for viewing and operating the meter. The over-molding rubber case protects the meter for better durability. A single 9 V battery (16 hours with alkaline battery) or the included 12 V power adapter (with model 879B & 880) can be used to power the meter, giving the user options for portable or bench-top use.

Model 880 includes a rechargeable Ni-MH battery that can provide up to six hours of battery life.

Four-terminal shielded configuration (880 only)

The 880 provides a 4-terminal socket with separate sensing and current leads plus guard terminal, a configuration typically only found in bench LCR meters. When using the included 4-terminal Kelvin test leads, this configuration can reduce the effect of lead impedances and contact resistance. This minimizes measurement errors and improves accuracy especially in the lower impedance range.

Faster Auto Range

The advanced auto range circuit design allows for faster measurements without the need to manually select ranges.

Dual Display

The dual display allows multiple measurements to be conveniently displayed at once.

Auto Detect Mode (880 only)

With the push of a single button, the Auto detect function will automatically identify primary parameters L, C or R and related secondary parameters, and set the suitable series/parallel equivalent mode and range.
