General introduction:

DTSF217 ( T9-1 ) Three Phase Four Wire Multi-tariff Electronic Meter supports import and export metering with TOU or step tariff functions . It can record various events and meter can be read during power outage

Main functions:

1. Data snapshot: It supports freezing which include daily freezing hourly freezing, occasional freezing, immediate freezing

2. Event logs: It can separately record latest 10 times events, such as power outage, programming, time correction, meter cover open and terminal cover open, reset of events, reset of meter, etc.

3. Communication interface: The meter has one far infrared interfaceone RS485. Interfaces are independent. The protocol of meter conforms to DL/T645-2007
