Performance and features
1. The testing current is high enough to fully meet the requirements indicated in the national standards for testing of contact resistance;
2. A high output voltage, a wider measuring span up to 100MΩ;
3. The test current is supplied by a high precision, switching type current constant power supply (200A), and therefore with no needs to be adjusted, so that a fast and accurate measurement can be provided.
4. Wiring through four terminals effectively eliminates impacts on the test results caused by the resistance of test wires;
5. The product provides faster test, indicating results 5 seconds or so after test start-up;
6. The product equipped with over-heat protection circuit can be continuously work for a long time and therefore provides high reliability and stability;
7. The product is an easy operation, lightweight type and applicable to field use.
