XW-1100 100A Loop Resistance Tester / Contact Resistance Tester / Micro-Ohmmeter /Circuit Resistance Tester
1. Brief introduction
This product is a high-precision digital resistance testing instrument carefully developed by our company according to IEC standards and relevant national regulations. It can be used for measuring the contact resistance and loop resistance of various switches and electrical appliances, and the contact resistance of cables, wires, and welds.
2. Functional features
- The whole instrument is controlled by a high-speed single-chip microcomputer, with a high degree of automation and simple operation.
- 480 * 270 true color LCD touch screen, clear display under strong light, two operation methods: touch screen/key.
- RS232(optional) and USB interface; can communicate with a computer and U disk storage.
- Adopting the four-terminal method effectively eliminates the influence of test line resistance on the test results.
- The response speed is fast, the measurement data is stable, and the data is refreshed automatically during the test process.
- Intelligent power management technology can effectively reduce the internal heating of the instrument and save energy.
- The protection function is perfect, and the performance is more reliable.
- Equipped with a micro printer to print test data at any time
- Non-power-down clock and non-power-down memory can permanently save data.
