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.

40,000-Count Dual-Display Handheld LCR Meters
Models 878B, 879B, and 880
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.
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.
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.
