SMART TWEEZERS Professional High-Precision R-L-C Meter

SMD Pre-Calibrated Components Identifier in a Set of Tweezers

For the users who already have  ST-AS SMT Smart Tweezers:

We offer now the Retro kit: P/N ST-CH Kit to upgrade Smart Tweezers ST-AS to ST-R Model with re-chargable batteries

ST-CH Kit

The ST-CH Kit includes the above shown parts which can be installed into ST-AS to convert them into ST-R and the charger (Power Supply and the Base).
The retro instruction sheet for a technician explaining how to perform the retro comes with the kit.

  • New Field Replaceable Tips
  • Dual Graphics Displays
  • Analog Bar Graph
  • Fully automatic measurement of Capacitance, Inductance, Resistance, Voltage, Continuity, Diode Polarity
  • Auto range: Meter automatically selects best range
  • Continuity / Open test: Beeper sounds for resistance readings below threshold, or to indicate a momentary open circuit
  • Trace Graph: Oscilloscope-like display for AC voltage measurement.
  • Convenient one-hand operation

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.

Voltage

The Smart Tweezers is able to measure voltage. In the AUTO MODE, it measures DC voltage from 100µV to 800mV. In the TRACE MODE, it shows an oscilloscope-like picture of AC voltage.

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.

SMT Smart Tweezers With a Charger Model ST-R

This is a new model which comes with the inductive charger and needs rechargeable batteries.

SMT Smart Tweezers Model ST-R is equipped with an inductive coupling board and rechargeable batteries. This model is recommended when "SMT Smart Tweezers" are used for more then 2 hours a day. It has an alternative for the power source. Can use either a USB connector or a regular wall power outlet. If anyone wants to upgrade the previous models of the SMT Smart Tweezers they can purchase an upgrade kit through www.bomir.com or can send the unit to our service department for an upgrade.
