1. energy measure:
forward and reverse energy records in separately,
can set LCD display according to customer's require (forward energy display, reverse energy display, forward energy+ reverse energy
display, forward energy- reverse energy display)
2. Demand measure: 15 minutes block type maximum demand measure, it can reset through bottom, accumulate present maximum
demand to cumulative demand when reset.
3. timesharing measure: four tariff timesharing measure, two time interval tables, Monday, Tuesday, Wednesday, Thursday, Friday,
Saturday and Sunday.
4. Historical energy: above tariff energy can save last 3 months Historical data separately.
● Curve and event
1. Curve includes: grid frequency, meter temperature, grid voltage, A channel current, B channel current, instantaneous total power and so on. 15 minutes one point, save 35 days at most.
2. Event log:
grid frequency upper limit, grid frequency lower limit, meter temperature upper limit, meter temperature lower limit, grid voltage upper limit, grid voltage lower limit, A channel current upper limit, B channel current upper limit. These upper and lower limit value can set. Event records with time, date and value. Last power Failure record with time and duration time.
Above event all can record 64 times.
3. 15 minutes energy: Can record whole energy each 15 minutes and display on the LCD for last 15 minutes energy, it can records 35 days.
● Communication function
1.Infrared communication: can proceed basic set and test for meter by Infrared
2.GPRS: can proceed remote control for meter by GPRS, includes read all meter data and set meter. It can remote control load( disconnect and connect internal relay). Meter send data for power off which with meter address to master server only one time.
