Smart Tweezers is an R-L-C meter in a set of tweezers. Smart Tweezers features a unique patented mechanical and electronic design that incorporates a built-in direct precision SMD probe designed for component evaluation on the production line, component impedance testing and sorting of SMD components. Smart Tweezers dramatically cuts the time necessary to troubleshoot and debug a complex PCB making process of locating of a faulty component a breeze.

The integrated SMD probe and graphic display, combined with automatic recognition of measurement modes (R, C, and L) and the range of measurement, allow the operator to focus on the component under test. As a result, testing, sorting and evaluation of components become more efficient and cost effective.


Inductance, Capacitance, Resistance
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). When multiple features present, the secondary display shows one of the values. The Bar Graph provides an analog indication of the measured input.

Continuity/Open Test
The Smart Tweezers is designed to measure continuity. The beeper sounds for resistance readings below the threshold, or to indicate a momentary open circuit.

Durable Probes
Tweezers tips are made of gold-plated non-magnetic stainless steel.

Ergonomic Design and Convenient Controls
Smart Tweezers features a JOG DIAL button to choose modifiers for a selected function or change the setting. Rotate the JOG DIAL button to choose from a list of functions, then press to activate this function and see it appear on the display.
