Generate trend curve, the interval time of recording is able to set, collect once for 5s and can stored 75days.

Alarm function

Users can set up 40 groups alarm monitoring project, each group can set different judgments parameters (including 50 harmonics a total of 123 different parameters), can be set different alarm threshold, how long it will take to produce the alarm when over the critical value is can be set, etc. Can store up to a maximum of 12800 set alarm record.

Screenshots function

In any test page screenshots can store the current screen, automatically records the time and test mode at the same time. Such as save the current voltage wave, harmonic bar charts and phasor diagram, etc. Screenshots can be saved up to 60 groups.

Communication function

Communicate with computer by USB interface, monitoring software can display waveform of power quality analysis, able to read those has been detected and captured like transient waveform, trend curve record, alarm list, test screenshots, etc.

Setting function

The user can set the time and date, set the display contrast ratio and brightness, set each corresponding color of each phase line in the instrument

The connection mode of instruments and the grid type can be set

Can select different current clamp and different voltage test strain ratio

Can be selected menu in Chinese or English menu

Chinese/English help menu
