JD-100A Intelligent Circuit Resistance TesterDetailed product description：

According to the new "Regulations for Handover and Preventive Testing of Power Equipment", the measurement of conductive circuit resistance of various switchgear shall not be less than 100A. In response to this, our factory has designed and developed a new generation of intelligent circuit resistance tester products in accordance with the new regulations. This product is suitable for testing the contact resistance value of the main contact of high and low voltage switches, as well as the DC resistance value of high and low voltage cable lines. The JD-100A intelligent circuit resistance tester adopts a 100A constant current output. The maximum output voltage can reach 10V (2-3 times that of conventional instruments), which can be tested using thin load lines, greatly reducing the labor intensity of on-site testing personnel. The testing process is entirely controlled by a single chip and automatically implemented, with high accuracy, good repeatability, single button operation, simple and easy to implement. The test data is displayed on LCD and the results are printed. Suitable for different work environments.

working principle
The JD-100A intelligent circuit resistance tester is equipped with a built-in 100A switching power supply, which enables real-time tracking testing of two sets of circuits with a constant current of 100A. Ensure that the test results are correct.

Operating Procedure for JD-100A Intelligent Loop Resistance Tester
1. Connect the wires according to the four terminal connection method.
2. Turn on the power.
Press the measurement/print button (if the current display shows A value less than 100A/200A, it can be corrected by adjusting the panel current).
After measuring the displayed value, the data needs to be saved. Press the measurement/print button for three seconds to print the data.
After the measurement is completed, please turn off the power.
Please take good care of the testing pliers.
