6) Deviation of RTC: ¡Ü0.5s/D (23¡À3¡ãC)
7) Backup lithium battery working life: >10 years, Continuous working time: >3 years
8) Display: LCD display
9) Measure energy: measures total, peak, shoulder and trough accumulative active
energy of three phase, measures total, peak, shoulder and trough active energy of
phase A, B and C respectively, and measures total reactive energy and reactive
energy of phase A, B and C respectively. The record content is current and previous
six months
10) Measure demand: measures total maximum demand and the occurred time of
active energy for current and previous 6 months
11) Tariff and time period: three tariffs for active energy (peak, shoulder and trough),
and can set at most 8 time periods per day
12) Real time data: voltage and current for phase A, B and C respectively, and active
power, reactive power and power factor for each phase and total
13) Has infrared communication interface, with the communication protocol conforming
to DL/T645-1997 and the communicating baud rate is 1,200bps
14) The built-in carrier wave module can realize carrier wave meter reading and
setting functions
15) Records the latest ten times of starting and ending time of the power off for the
electric meter
16) Records each phase's phase loss accumulative time and times and its latest ten
times of starting and ending time
17) Records the accumulative time of the cover opening and the latest opening time
18) Has key-press display and automatic recycle display and the recycle display
content and time can be set
19) Records the load curve: selected from the total active energy and total reactive
energy, and the recording time interval can be set
20) Freezes billing readings on reading date at the end of a month, and also can use
broadcasting order to freeze the energy for current uniformly
21) Has controlling function: the output relay controlling interface is used to control
external device
22) Monitors the case opening, EEPROM error, clock error and low voltage of the
battery, and can alarm through displaying
Three Phase Carrier Wave Electric Energy Meter
