The loop resistance tester is designed by combining high-frequency switching power supply technology and digital circuit technology. It is suitable for measuring the loop resistance of switch control equipment. The test current adopts DC 100A and 200A recommended by national standards. The loop resistance can be directly measured at a current of 100A or the loop resistance can be directly measured at a current of 200A. The final test results are all displayed in numbers. skills: ⒈ Loop resistance tester is connected according to four-terminal connection method. ⒉ Turn on the power of the loop resistance tester. ⒊ The loop resistance tester can press the measurement key (for example, after the current display A value is less than 100A, it can be corrected by the panel current fine-tuning). ⒋ After measuring the displayed value, you need to save the data. ⒌ After measuring, please turn off the power. ⒠Please take care of the test pliers.
