optical power meter ,power meter, digital power meter I Metering & Measuring 1.Metering both forward direction and reverse active energy at intervals , and saving the latest three months` data 2. Metering both forward direction and reverse reactive energy can be metered at intervals ,and saving the latest three months` data 3. Metering the total active energy and the total reactive energy, and saving the latest three months` data 4. Metering the four quadrants` reactive energy, and saving the latest three months` data 5. Metering the maximum demand and their occurrence time; and saving the latest three months` data 6. The period of maximum demand can be set at 5, 10, 15, 30, 60 minutes. power meter II. Multi-tariff function 1. four tariffs, 12 intervals and 5 days intervals, 4 time zones, public holidays 2. Standby time interval shifting, and record shifting times, shifting time and energy consumption when shifting, after the normal time checkup it will shift tariff immediately 3. clock chips are out-built and with temperature compensation IV. Display/Indication 1. button display, automatic display and reviewing data with remote control 2. When power fails, the meter can be activated through button or infrared and meter data also can be read through infrared. 3. Information code can be checked up automatically and displayed every one minute. 4. wide LCD screen display V. Communication 1. Two circuits RS-485 port, suitable to baud rate 1200-9600bps, infra red port and wave carrier port, PC or HHU, these three communication ports can communicate with meter simultaneously, thus realizing the real multi-communications and without mutual interference. optical power meter ,power meter, digital power meter
