III. MAINFUNCTIONS
3 . 1 Energy measurement
The meter measures positive and negative active energy of single phase two wire power system with six tariff function . Previous 24 months active energy data are stored in the meter. The active energy data can be read via LCD or optical port
The meter has non-volatile memory (NVM) that can retain data up to 30 years in case of power failure .
3.2 Maximum demand
The meter calculates and store active demand for an integration time of 30 minutes and records MD, date and time . Previous 12 months’ MD is stored in NVM with occurring date and time. The maximum demand shall automatically be reset at 24:00 o 'clock of the last day of each calendar month.
3.3 LCD Viewing data
Meter LCD provides auto-scrolling mode and manual scrolling mode to display parameters. For auto- scrolling mode, the display time of each screen is 10 seconds. For manual display mode- 1 , under auto-scrolling mode and press the button to page turn display the content of manual display mode- 1. under auto-scrolling mode and press the button to hold 3 seconds, meter goes into display the content of manual display mode-2. After one minute, the LCD will go back to the auto-scrolling mode.
At power off condition, meter display can be activated by press the button and goes on auto-scrolling mode and display cumulative kWh for 20 seconds. And then it switches off display and goes back to the sleep mode.
LCD provides 8 big digits (No. of digits for energy 6 digits,No. of available decimal,2 digits) for main parameters display. The big digits size is 5 * 10 mm which is wide viewing angle and visible from a distance.
