| Abstract: | Referring to the baseline of high precision, samples of voltage, electric current and resistance are adjusted towards the same direction by adaptive technology. The measurement precision and anti-interference ability are improved by digital filters technology, which leads to the improvement on the ratio of quality to price. The range of measurement is enlarged and users feel more convenient by using the programmed gain control. The management computer adopts RS-485 communication method to network with workstation, monitoring the workstation in real time, and provides the opportunity to incorporate in power network. |
