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

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.

Applications

nꢀ Passive component troubleshooting

nꢀ Electronic assembly

frequencies up to 100 kHz, selectable test signal

levels and measurement rate.

nꢀ Quality control (component sorting)

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.

Connectivity

Free downloadable software is available for your

handheld LCR meter. View and log measurements

and setup and conﬁgure the instrument’s

measurement parameters.

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.

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.

Model 880 includes a rechargeable Ni-MH

battery that can provide up to six hours of battery

life.

Four-terminal shielded conﬁguration

(880 only)

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.

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

Notes: Equivalent series resistance (ESR) accuracy for the 880 is calculated according to the following formula:

R_se

X_xx Ø_e

180

where X_xis the measured impedance, 2πfL_xor

, and Ø_eis the phase angle accuracy, θ_ex

2πfC_x
