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, measures ESR and impedance Z.

Smart Tweezers™ 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 Components

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 leads made by IDEAL-TEK S.A. of Switzerland are able to reliably contact SMD components (as small as 0201 format) or take measurements from the devices already mounted on a board.

Capacitor ESR Meter Mode

Smart Tweezers™ feature a ESR Meter/Tester mode for quality testing of high value capacitors.

Perfect for Conventional Components

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 battery

Smart Tweezers™ comes equipped with a built-in high-capacity Li-Ion rechargeable battery.
Battery replacements are not required.

Universal 110-220V power supply and Micro USB charging cord are included.

Automatic Component Recognition

Resistance, capacitance and inductance can be measured with automatic selection of the test parameters and test range.

Smart Tweezers™ 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).

Ergonomic Design and Convenient Controls

Default settings can be modified by navigating a set of menus with the Navigation Control.

Meter’s display can be easily flipped from the menu for left-handed use.

Continuity/Open Test, 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 in-circuit tests.
Variable test signal output from 0.5 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 measurement precision.
