Features :
The positive and negative accumulated electricity in each time period (i.e. each shift) and the daily electricity consumption can be measured separately.
Measure, record and display the current operating parameters of the electric energy meter, such as voltage, current, power, power factor, etc. The measurement error shall not exceed ±1% .
Independent RS485 communication, infrared communication, and carrier communication interfaces.
Event metering function: record the zeroing time of the energy meter, total number of voltage loss, total number of time calibration, total number of power failures, etc.
It has a shift schedule, supporting at least 4 shifts. It has a calendar and clock, and can program at least 4 time periods and at most 14 time periods within 24 hours ; the minimum time interval between time periods is 60 minutes ; time periods can be set across zero o’clock.
LCD display can show the current monthly power consumption, time, voltage, total 1234 shift power consumption and other information, with automatic cycle display and key display.
