Product Introduction
This product is a high-precision and digital resistance detection instrument elaborately developed by our company according to IEC standards and relevant national regulations, which can measure micro-ohm contact resistance. It is widely used to measure the contact resistance, loop resistance, cable wire and weld contact resistance of various switches and electrical appliances.

Functional features
The whole machine is controlled by high-speed single-chip microcomputer, with high degree of automation and easy operation.
Real color LCD touch screen, clear display under strong light, touch screen/button dual use.
RS232 (reserved) and USB interface, which can communicate with computer and have USB memory function.
The four-terminal wiring method is adopted, effectively eliminating the impact of the test line resistance on the test results.
Fast response speed, stable measurement data and automatic data refreshing during test.
Intelligent power management technology can effectively reduce the internal heating of the instrument and save energy.
Perfect protection function and more reliable performance.
Equipped with micro printer to print test data at any time.
Clock and memory without power failure can save data for a long time.
