1. Kelvin Fish Clamp Test Line, Wear-/-/Easy To Plug And Unplug 2. The Four-Wire Method, Which Also Call Four-Terminal Measurement Technology And Kelvin Measurement Method, Is An Impedance Measurement Method In Electronic Circuits And Is Mainly Used For Accurate Measurement Of Resistor Resistance. 3. The Voltage Difference Generated By Wiring Resistance And Wire Resistance Is Almost Zero And Does Not Affect The Voltage Measurement Results. 4. Contact Resistance. Since Only A Very Small Part Of The Current (So Small That It Can Be Ignored) Flows Through The Voltmeter, It Does Not Affect The Current Measurement Results. 5. Product Impedance, The Resistance To Be Measured Is Low Resistance, And Can Also Be Measured Accurately.
