komponenttester
A komponenttester is a measurement device used to identify and characterize electronic components by applying known test signals and observing the response. They are commonly used by hobbyists, technicians, and engineers to verify components such as resistors, capacitors, inductors, diodes, and transistors. Devices range from pocket-sized handheld units to benchtop instruments and often include accessories for SMD components and test leads.
Common capabilities include measuring resistance, capacitance, inductance, and dielectric properties, as well as the equivalent series
Technically, testers use various test methods, typically applying a small DC bias or an AC signal at
Open-source and DIY component testers have become popular, using microcontrollers and affordable sensors to provide basic
