Resistance tester is an indispensable tool for electrical safety inspection and grounding engineering completion acceptance. Including grounding resistance tester, insulation resistance tester, DC resistance tester, surface resistance tester and loop resistance tester. The loop resistance measuring instrument (RX transformer loop resistance tester) is suitable for testing the contact resistance value of the main contacts of high and low voltage switches and the DC resistance value of high and low voltage cable lines. The intelligent loop resistance tester uses 100A constant current output.
The maximum output voltage can reach 10V (2-3 times of conventional instruments), which can use a thin test line on the load surface, which greatly reduces the labor intensity of field testers. The test process is automatically implemented by single-chip control, with high precision, good retestability, single-button operation, simple and easy to perform, and test data displayed on LCD. Suitable for different working environments. The grounding resistance tester is a common instrument used to check and measure the grounding resistance. Due to the rapid development of computer technology in recent years, the grounding resistance tester has also penetrated a large number of microprocessor technologies. Its measurement of functional resistance and what types of resistance testers include The accuracy is incomparable with ordinary instruments.
