2.1 Features and Technical Parameters
Meter send data to CIU regularly, including the instantaneous data (such as voltage, current, power), energy consumption, balance credit, some parameters and event flag.
After CIU receiving data, will display the parameter information of corresponding meter.
2.1.1 Features
Anti-tampering
Support load ground connection, bypass detection, open cover detection, influence of external magnetic field, abnormal voltage record, two loop measurement.
Tariff
Divide into weekday timetable and weekend timetable, with 8 time period and 8 tariffs. Every timetable has a backup table for remote updating of backup timetable and configure the switching time. Meter will automatically switch the tariff table at the switching time.
Communication
Meter support radio frequency communication.
Event
Open cover, magnetic field, load ground connection, reserve current, over-voltage, low-voltage, low-frequency, overload, power-fail, low remaining power, and token record.
Measurement
Meter measures voltage, current, active power, reactive power, frequency, power factor, MD in the current month, MD of last 1 month, MD of last 2 month, the absolute value of total active energy, the absolute value of total active tariff energy, total input energy of the current month, total input energy of last 5 month, total output energy of the current month, total output energy of last 5 month, and total reactive energy.
Mode
Meter has 3 operation modes: STS token mode, currency prepaid mode and post-paid (traditional) mode, which can be switched.
And the currency mode can be divided into tariff mode and step price mode. Modes can be configured through communication.
STS operation
Enter 20-digit token via keypad of meter or CIU, the meter display will be green Pic 1 if recharging is successful, will be red Pic 2 if is failed.
