Many electronic systems suffer when contact resistance rises, and in this guide you will learn how small resistance changes can cause signal degradation, measurement errors, and intermittent faults that undermine system performance; you will also see how proper connector selection, surface preparation, and periodic inspection can improve accuracy and ensure [...]
You depend on stable on-resistance to minimize contact variability so your readings remain consistent over months or years. By controlling thermal, aging, and mechanical influences you reduce measurement drift, lower calibration frequency, and extend device reliability. Practical design choices-component selection, controlled stress, and real-time compensation-help you maintain predictable long-term accuracy [...]
Most systems suffer measurable performance loss from high contact resistance, so you should measure and monitor interface resistance, clean mating surfaces, ensure correct contact pressure, and use appropriate platings or lubricants to reduce corrosion. By taking these steps you prevent excess heat and failure risk and achieve higher efficiency and [...]
Measurement of contact resistance requires precise technique and safety: you will learn four-terminal (Kelvin) methods to achieve accurate low-resistance readings, how to design tests for consistent, repeatable results, and how to avoid hazards such as overheating, arcing, and equipment damage by controlling current, contact force, and proper fixturing. Types of [...]
