The log can contain up to 12,800 alarms.

◆Snapshot function

Any screen can be saved(screen snapshot), at the same time automatically records the time and test mode. Such as can save voltage and current waveform, harmonic bar chart, phasor diagram etc. It can save a maximum of 60 screen snapshot.

1.2.3. Other functions

◆Communication function

Communicate with computer via USB, Monitoring software can display waveform of power quality analysis, read of the transient waveform, trend chart recording, alarm log, screenshots, and display on the computer.

◆Setting function

The user can configuration of the time and date, configuration of the screen contrast and brightness, definition of each phase curve colours.

Choice of type of connection to the network.

Configuration of the type of the current sensors and voltage ratios.

Select Chinese menu or English menu.

◆Help menu in Chinese/English

Every stage of operation can press the "help" key to obtain relevant information.
