Anti-tampering
Support load ground connection, bypass detection, open cover detection, influence of external magnetic field, abnormal voltage record, live&neutral wire metering.
Anti-tamper when Neutral missing: when Neutral missing, the meter still can work（battery support）
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 4G communication, with fall back capability to 2G and 3G.
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 IHD, the meter display will be green Pic 1 if recharging is successful, will be red Pic 2 if is failed.
