The fault recorder adopts embedded structure and embedded operating system, the storage medium is electronic disk or CF card, and industrial computer or similar devices are equipped as the second data channel of local storage to realize dual data redundancy storage.

The fault recording screen body is equipped with a printer, which can print good graphic reports and has the function of "one key printing" automatic output. After starting the recording, it can automatically print the fault time, type, fault location, current and voltage data of no less than 10 cycles before and after the fault. And the printing time length of electrical waveform can be set by users.

Through the standard communication interface, remote programming and data acquisition can be carried out for the fault recorder. At the same time, it supports multiple communication interfaces to realize local and remote inquiry of fault recording information. The fault recorder has the function of local networking, local and remote communication interface, and the related software and hardware configuration. It can not only carry out signal monitoring, signal reset and control operation locally, but also carry out remote operation through interface. It can also interface with computer monitoring system through node mode, so as to realize the monitoring of fault recorder's fault alarm, start and other signals.

The fault wave recording record file adopts the cyclic storage mode. When the hard disk is full, the new data file automatically covers the early data file. The software design is advanced and reasonable. The operation, debugging and setting management are carried out through Chinese menu. The database has strong functions. It manages the recording data, fault reports, harmonic records, operation records, etc. it can search fault files according to time section and fault type, and supports fixed value backup and import.
