The display contents consist of Chinese characters, figures, process curves and bar graphics. By pressing the key on the panel, you can complete page turning, historical data search and modification of curve time scale, etc.
Data backup	Support USB and SD card for data backup and transfer, maximum capacity: 8GB, support FAT and FAT32 formats.
Storage capacity	Internal Flash storage capacity: 64M Byte
Time interval of recording	Time interval for selection: 1, 2, 4, 6, 15, 30, 60, 120, 240（Unit: second）
Time duration of storage (Continuous record without power failure)	4days（1-second time interval）5625 days（240-second time interval） Formula: (Note: Calculation of channel number: The program will divide the channel into five classes of 6, 16, 32 and 64. When the channel falls within the range of two classes, the bigger one should be taken. If, for instance, the channel number is 12, the number of 16 should be taken as the channel number.)
