Key benefits Voltage measurement accuracy: The voltage drop caused by wiring resistance is negligible, ensuring voltage measurements are not affected by lead resistance. Reliable and easy connections: Kelvin Fish Clamp Test Line is designed for durability and offers easy plug and unplug operation to speed setup. Minimal impact from contact resistance: Only a very small portion of the current flows through the voltmeter, so contact resistance does not affect current measurement results. precision resistance measurement: The fourwire method, also known as fourterminal or Kelvin measurement, is an impedance measurement technique used in electronic circuits and is primarily for accurate measurement of resistor resistance. What it is and how it helps The fourwire method enables impedance and resistor resistance measurements with reduced lead and contact errors, delivering reliable data in precision work. This approach is suited for scenarios where measurement accuracy is critical and wiring or lead resistance could otherwise skew results. Use scenarios Calibrating precision resistors in research and development laboratories or test stations. Verifying resistor values during electronics assembly or troubleshooting to avoid leadresistance bias. Conducting impedance measurements in electronic circuits that require accurate resistor values, especially for lowvalue or sensitive components.
