After a monitoring system enters the commissioning phase, the commissioning phase, and after delivery, there may be such a failure phenomenon, such as: failure to operate normally, technical specifications that the system does not meet the design requirements, overall performance and quality are not ideal, that is, Some "soft problems." These problems are inevitable for a monitoring project, especially for a complex, large-scale monitoring project. The monitoring system consists of a main monitor, a battery inspection instrument, an operation interface, and a branch feeder insulation detection sensor. Full-featured, intelligent control, unattended, with automated integrated management interface. 7.7-inch color DSTN LCD screen, 640 × 480 pixels. Data recording, power down retention. In theory, quality problems can occur with various equipment and components. However, from the experience point of view, the quality problems of the products themselves are mostly on the decoder, electric cloud platform, transmission components and other equipment. It is worth pointing out that some equipments may not have the problem of being unusable in quality as a whole, but from some technical indicators, they fail to reach the indicators given in the product manual. Therefore, the necessary sampling tests must be performed on the selected products. If it is a product quality problem, the best way is to replace the product, and not to disassemble and repair it.
Features:

one. startup screen:
Press the start menu or each function block and the screen expands as follows:
The AC power failure is more than ten minutes, or the battery float current is greater than the quarter of the set charging current. The system automatically turns to equalize charging. First, the constant current charging is performed according to the set charging current. When the voltage reaches the set charging voltage, the constant current is turned. Pressure charging, when the charging current of 0.01 C is reached, three hours of constant voltage charging is performed until the end of charging. It can set the charging time of up to 72 hours for the initial charge.
