High Speed, High Precision LCR Meter in Tweezers
Wide measurement range starting from
0.5pF, 0.5μH and 50mΩ

Battery and Micro USB Charger
Smart Tweezers™ is a
handheld electronic tool of a new concept.
Its unique design combines a pair of gold-plated
SMD tweezers with ergonomic shielded handles and a precise
full featured LCR impedance meter in
a compact, lightweight instrument.
Smart Tweezers™ measures
electronic component's capacitance, resistance and
inductance with high speed and
precision by evaluating circuit impedance.
Additionally it tests diodes,
ESR and impedance Z
provides a perfect solution for testing and identification
of Surface Mount Devices (SMD) as well as
for troubleshooting of complex electronic systems.
Handy Tool for Tiny SMD
Surface mount devices are
usually tiny and without wire leads, making it more difficult
to test and identify SMD than conventional components.
Smart Tweezers™ gives users an
easy way to sort and evaluate loose components and to perform
on-board measurements and debugging.
Precise gold-plated tips made
of non-magnetic steel
are able to pick and reliably contact even smallest SMD
components (as small as 0201 format) or take measurements
from the devices already mounted on a board. The probe can
also be used to test conventional components with wire leads
too short to insert into the test terminals.
Tweezers™ greatly simplifies testing and
Smart Tweezers™ works fine with
conventional though-hole electronic components. The unit
helps to verify values with high speed and precision.
Built-in Li-Ion Polymer Rechargeable
Smart Tweezers™ comes equipped with a
built-in high-capacity Li-Ion rechargeable battery. Battery
replacements are not required.
power supply and Micro USB charging cord are included.
automatically determines type of the component (resistance,
capacitance or inductance), selects proper range and signal
frequency for highest accuracy measurements. Manual
overrides are available as well.
Unit’s display clearly indicates
the type of the component, measurement result and test
conditions. The primary display
shows the present reading. The secondary display (on
top) shows the present reading of additional parameters or
measurement conditions when the primary display shows some
other feature (L, C).
Resistance, capacitance and inductance can be measured
with automatic selection of the test parameters and test
Design and Convenient Controls
Default settings can be modified by navigating a set of menus with the
Meter's display can be easily flipped from the menu for left-handed use.
Diode Polarity Testing, Additional Parameters and Modes
Smart Tweezers™ LCR meter
allows to test various
component types, including
secondary components of Dissipation
Factor (D), Quality Factor (Q).
The built-in Equivalent Series Resistance (ESR) mode
helps you better understand the inherent resistance -
behavior typically found in capacitors across selected
frequencies.In its DIODE mode Smart
Tweezers™ tests diode polarity
and indicates if it is short.Smart Tweezers™ has a continuity
detector. Variable beeper sounds
for resistance reading below
set thresholds. Additionally, this
function helps to locate shorted
conductors (e.g. on a PCB).In manual modes Smart
Tweezers™ measures a specific
circuit parameter — L, C, R, Z or
ESR. Manual modes also improves
component type identification for
Variable test signal output from
0.25 to 1.0Vrms allows to improve
test precision in different situation
e.g. for in-circuit measurement and
loose leaded ceramic capacitors. Visible and audible tolerance
mode allows to perform
component sorting. Math null function allows to store a
pre-measured offset and improve
