BK Precision 878B - 40,000 Count Dual Display Handheld LCR Meter

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.

Easy Front Panel Operation

Powerful Features

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.

Increase Productivity with PC Connectivity
Free downloadable software is available for your handheld LCR meter. View and log measurements and setup and configure the instrument’s measurement parameters.
