Contact resistance increases due to contact surface oxidation, poor contact fastening and other reasons. The Test procedures require conductive contact resistance testing of various switchgear and cable connectors, the test current shall not be less than 100A. When the high current flows, the temperature of the contact point rises, which accelerates the oxidation of the contact surface and further increases the contact resistance will lead to serious accidents. Therefore, it is necessary to measure the contact resistance often or regularly.
| Test current | Test range | Accuracy |
| 400A | 0~10mΩ | ±(0.5%rdg+0.2μΩ) |
| 300A | 0~15mΩ | |
| 200A | 0~25mΩ | |
| 150A | 0~30mΩ | |
| 100A | 0~50mΩ | |
| 50A | 0~100mΩ |
