When the measured resistance is less than a few ohm, the resistance of the test lead and the contact resistance of the probe can not be neglected and timeless compared with the tested resistance. If the two-wire test method is still used, the test error will increase. At this time, Kelvin connection mode (or four-wire test mode) can be used for testing. ETA3105 adopts four-wire test of Kelvin method, Kelvin clip and half of the clip are insulated from each other. Only the measured conductor contacts the tip of the clamp. Gold plating of the clip can stabilize the passage of current, alleviate the corrosion interference of the probe using environment and improve durability and wear resistance.

Characteristic:

- 4-wire independent connection alligator clip, eliminating lead error.

- Low resistance measurement of gold plating process is more stable.

- The workmanship is exquisite, and the details of the mould pressing are processed to improve.
