Communication with IHD:
It can communicate with the X899001 handheld Bluetooth display to realize the matching and recharge function. The distance can be 50meters.
Support load ground connection, switch detection, influence of external magnetic field, abnormal voltage record.
Anti-tamper when Neutral missing:when Neutral missing, the meter still can work（battery support）
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.
Meter support IR,RS485/LoRa, baud-rate: 9600/PLC, baud-rate: 4800.
Open cover, magnetic field, load ground connection, reserve current, over-voltage, low-voltage, low-frequency, overload, power-fail, low remaining power, and token record.
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.
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.
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.
