In order to eliminate the errors caused by lead resistance, ETA4553 adopts four-wire Kelvin method to test the micro resistance. The probe position is 4-point telescopic probe. The single-axis shape design is designed to meet the needs of precision products with narrow measuring position. The probe gold plating process can stabilize the passage of current, alleviate the corrosion interference of the probe environment and improve durability and wear resistance. 4 mm standard banana plug can be used in 4-wire resistance measuring instruments such as micro-ohmmeter, desktop multimeter, battery internal resistance tester, etc. It can be easily used in production line, acceptance testing and other fields.
