Introduction to the functions and parameter settings of the water quality online monitoring system

KNF-407 Water Quality Online Monitoring System can be used in real-time monitoring of water quality in rivers and other environments. Its functions are different from other equipment, and different methods are required when setting parameters. Let me introduce it to you below. Function introduction of water quality online monitoring system 1. There are five buttons at the bottom of the screen display main interface (parameter setting, data table, historical curve, alarm record, data export). 2. Parameter setting: Press this button to switch the parameter setting interface and set the basic parameter information. 3. Data table: You can switch to the data table interface through this button, and the monitoring data is displayed in table form. 4. Historical curve: This button can be used to switch to the historical curve interface, and the historical data of any parameter can be viewed by operating the curve interface. The historical curve interface is also the main interface. 5. Alarm record: Through this button, you can switch to the alarm interface, and you can query the historical alarm data of any time period. 6. Data export: After the user logs in, insert the U disk to operate. Click the data export button to export historical monitoring data. When the collection interval is set to 1 minute/group of data, at least 300 days of data can be saved, and the data storage is full. After that, the data on the start date of the time will be automatically overwritten. In order to avoid data loss, the stored data should be exported in time before the expiration date is reached. Water quality on-line monitoring system parameter setting When you need to modify the system parameters, you can enter the parameter setting interface through the parameter setting button, and you can operate parameters such as upper and lower limits, sampling interval, saving interval, and backlight time. After modifying the parameters, the upper and lower limits of the alarm can be set for the parameter early warning value (the equipment has been set in accordance with the relevant national regulations before leaving the factory). When modifying the sampling interval, the reading time interval of sensor data can be controlled, and the default time is 60S. Modify the save interval to modify the time interval for saving data to the memory chip of the collector, and the default time is 30 minutes. Modifying the backlight time can control the display time of the data logger screen. When the logger is in the backlight off state, you only need to tap the screen to turn it on. Click the temperature selection to switch the acquisition temperature, usually pH sensor temperature or turbidity sensor temperature. Click Restart to restart the system. The saved data file name is the file name displayed when the data is exported, so try not to modify it, and its name is the same as the device number. KNF-407 water quality online monitoring system has different functions from other equipment, so it can show different functions, and the correct method should be followed when modifying system parameters.
