Digital Meters Measure Components
Handling SMT components and traditional components as small as 0.3 mm with wire leads too short to insert in test terminals, Aven’s two new battery-powered Quick-Test Tweezers incorporate a digital meter in a “tweezer” form factor for inspecting incoming circuit boards or loose components, as well as troubleshooting and production checks by electronic manufacturers. The instruments can perform AC or DC voltage measurements, check a component’s impedance (inductance, capacitance, and resistance), test diode polarity, or measuring currents in operating circuits. The digital readout shows the type of component, measurement result and test conditions, and a bar graph displays an analog indicator of measured input. Applications include electronics R&D, manufacturing, maintenance, and training.
