Quick-Test Tweezers Ease Electronics Diagnosis


A compact, lightweight digital meter integrated with comfort-grip tweezers allows fast, precise measurements of small components and circuits.
     Newly introduced Quick-Test Tweezers simplify quality assurance inspections of incoming circuit boards or loose components, as well as troubleshooting and production checks by electronic manufacturers. Two models of the versatile tweezers are the latest additions from Aven, Inc., a Michigan supplier of high-performance  electronic and optical inspection tools.
     "Quick-Test Tweezers are an economical, handy replacement for bulky LCR multi-meters," says Mike Shahpurwala, president and marketing director at Aven. "These value-priced instruments allow one-touch identification and testing of SMDs, as well as short-circuit diagnosis or PCB extraction."
     Because surface mount devices usually are tiny and lack wire leads, they're harder to test and identify than conventional components. The newest battery-powered tweezers are a practical solution, and also can check traditional components with wire leads too short to insert in test terminals.
     One-hand use allows note-taking while checking a component's impedance (inductance, capacitance and resistance), testing its diode polarity or measuring currents in operating circuits. The AutoScan model immediately recognizes whether a component is a capacitor or resistor, with no mode change needed.  
     An oversize digital readout clearly shows the type of component , measurement result and test conditions. A bar graph displays an analog indicator of measured input.
     Applications include electronics R&D, manufacturing, maintenance and training.
     Quick-Test Tweezers are a value-priced adaptation of earlier-generation electronic testers that also combine mechanical and metering capabilities, according to the company. These are among practical features of the new models:                    
•    Accuracy matches or exceeds conventional professional devices.
•    Measures voltage and checks operation of printed circuit board (PCB).
•    Precise tips handle components as tiny as 0.3 millimeters.
•    AC or DC voltage measurements.
•    Displays active and reactive impedance components.
•    AutoScan model automatically identifies component and measures inductance, capacitance and resistance.
•    Light weight (under two ounces) and ergonomic design reduce fatigue or strain.
•    High-visibility bright yellow case makes tool easy to find.         
•    Long-lasting battery.
