4. Main function

4.1 Measurement function:can measure positive and reversed direction active energy.

4.2 Measured by different time segment

Can set up four rates(tine,peak,level,off-peak),eight period of time,the minimal time interval should be 5 minute

Can save the rates of 12 months including this month

Date of automatic meter reading is at 0~23 on 1~28

4.3 Measured by different time segment in reversed direction

Power direction can be identify automatically, reversed power can be saved automatically, at the same time it can be accumulated into positive power counter, automatically record reversed power, reversed starting time and reversed runtime

Have function of reversed pulse testing and indication

4.4 Communications

Have one RS485 communications port and one infrared communications port

RS485 communication port and internal meter electrical isolation,it also have lightning protection circuit.

Two directions of modulating infrared communications port

4.6 Other function

Adopt two-stage protection of password and Code Switch, when reading meter automatically recording last time program and programing times

Adopt clock circuit of hardware

Backup battery adopts imported green environmental disposable

Can set meter number, office number, period of time,rate,date,password, the content of display in a cycle and starting power.

Have function of marking backup battery detecting low voltage indication ,meter state of hardware. state of clock,meter direction.state of check.state of present.

Mark of can be read though RS485 or handheld PC

When press blue botton on the box,we can check electricity parameter customers have chose.
