It finished parameter setting and remote purchasing through RS485, carrier and other virtual medium..
It can measure and monitor operating parameter such as voltage, current (including zero line current), power, power factor and etc. The error would not exceed ±1
e) Recording the last 10 times for switch out and on by remote control, and also the time for switch out/on, power and etc.
f) Recording the total times for opening meter cover, the time for last 10 opening happened and finished.
a) The following information would be displayed in meter:
b) The unit for power is kWh, and 8 digital display, including 2 decimals.
c) LCD backlight wake up methods including switch wake up, infrared wake up(any infrared can work) and etc. In normal use, the life time for LCD won’t be less than 10 years
d) When power off, the backlight can be woke up by switch; If no operation after waking up, LCD would close automatically after a cycle; If operation exist, LCD would close automatically in 30 seconds after operation.
e) Indicator: --Pulse Red, it is off in normal condition, and would be flash when measuring active power
--Alarm Red, it is off in normal condition, and would be on when alarming
--Trip Yellow, it is off in normal condition, and would be on when load switch disconnect.
When the following faults or alarm appear, LCD would stop on the certain code and backlight keep on.
Err-01 Control Loop Error
Err-04 Low Voltage for Clock Battery
Err-08 Clock Error
Err-10 Error for Certification
Err-16 Error for Key Correction
Time Freezing: Freezing meter data according to the promissory time and interval; It can keep at least 12 times for each frozen fraction.
Instantaneous Freezing: Under improper condition, freezing current date time, all power and important measurement data; It keeps the data for last 3 times.
Appoint Freezing: In any case of older/new tariff, step tariff changeover and other situation which is necessary, the meter would freeze power and other important data on the changeover time, It keeps the data for last 2 times
Day Freezing: Store power on 0.00am for each day, total for 2 month
On Hour Freezing: Store active power for hour or half an hour, total for 96 data
Build in clock circuit with temperature compensation function, the calendar, timing, leap year can be changed over automatically. The output frequency for inner clock terminal is 1Hz. Between -25℃ to +60℃, clock accuracy is no more than ±1 s/d; Under reference temperature 23℃, clock accuracy is no more than ±0.5 s/d.
The accepted time broadcasting is no more than 5 min. No need to match with programming switch and communication password when time broadcasting. It can be set according to the inquire, and it avoid from handling in 5 min at the time when freezing or data storing.
9) Pulse Output
Meter has function for LED pulse and electrical pulse output which comes direct ratio with measuring energy. Optical test output device should comply gb/t17215.211-2006, electricity test output device should comply GB/T15284-2002. It has signal output terminal for clock, and the output frequency is 1Hz
10) Load Switch
External load switch, there is a group of switch signal for meter output. Volume of switch point is AC 220V/2A. Under normal condition, switch signal for output should keep switch on of load switch, allow for power on; When reach certain condition, switch signal for output should drive operation for external load switch, power off.
