1. Kelvin Fish Clamp Test Line, Wear-Resistant/Corrosion-Resistant/Easy To Plug And Unplug<br> 2. The Four-Wire Method, Which We Can 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.<br> 3. The Voltage Difference Generated By Wiring Resistance And Wire Resistance Is Almost Zero And Does Not Affect The Voltage Measurement Results.<br> 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.<br> 5. Product Impedance, The Resistance To Be Measured Is Low Resistance, And Can Also Be Measured Accurately.<br> Product Model:J.70075<br> Connection Method: fer<br> Surface Treatment:Nickel Plating/Gold Plating<br> Overall Length:Line Length 1m<br> Note:Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use.<br> Color:As Shown<br> Material:Copper+PA+ABS<br> Size:about 123mmx21mm<br> Package Contents:<br> 1 String * Black Low Resistance Tester Cables<br> 1 String * Red Low Resistance Tester Cables<br> Only the above package content, other products are not included.<br> Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
