Resistance Measurement Accuracy
| Measuring current | Measuring range | Precision | Resolution |
| 20A | 10.0uΩ~1000.0uΩ | ±0.2%FS±10dgt | 0.1uΩ |
| 1.000mΩ~10.000mΩ | ±0.2%FS±10dgt | 0.001mΩ | |
| 10A | 10.00mΩ~100.00mΩ | ±0.2%FS±10dgt | 0.01mΩ |
| 5A | 100.0mΩ~1000.0mΩ | ±0.2%FS±10dgt | 0.1mΩ |
| 1A | 1.000Ω~10.000Ω | ±0.2%FS±10dgt | 0.001Ω |
| 0.1A | 10.00Ω~100.00Ω | ±0.2%FS±10dgt | 0.01Ω |
| 10mA | 100.0Ω~1000.0Ω | ±0.2%FS±10dgt | 0.1Ω |
| 1mA | 1.000KΩ~10.000KΩ | ±0.4%FS±30dgt | 0.001KΩ |
| 10.00KΩ~100.00KΩ | ±0.4%FS±30dgt | 0.01KΩ | |
| 100.0KΩ~1000.0KΩ | ±1.5%FS±50dgt | 0.1KΩ | |
| Temperature characteristics: plus test accuracy × 0.3/°C within the operating temperature range. (outside 18°C to 28°C) Calculation method: accuracy = (accuracy of current gear) + 0.3×(number of temperature difference)×(accuracy of current gear) Example: use the environment 8°C/20A current file, the accuracy of this file is ±0.2%FS±10dgt Accuracy = (0.2%FS±10dgt) + 0.3×10×(0.2%FS±10dgt) = 0.8%FS±40dgt (Note: 1mA current 1000K gear test accuracy is only valid at 18°C to 28°C) Long-term testing of high-current gears is prone to heating and affecting accuracy. If there is any deviation, you need to wait for a while before testing. |
