Shape size: 96mm×48mm×75mm, Open hole: 92mm×44mm

Ⅰ、Survey:

D series intellective electric meter（Digital Ammeter、Digital Voltmeter、Frequency Meter、Tachometerand so on）is a type of multifunctional compositetype meter, it apply to electric power and electric network, field monitoringand display of automatic control systems and remote control and measurement ofautomatic dispatch telemechanical device，its function is to output standard current or voltage transfer signal using CPU operation electricnetwork’s parameter, such as current、voltage、3 phase power、frequency and so on，and then A/D’s conversion. Also this meter has RS232 or RS485communication interface be joined with long range data terminal TRU.

Ⅱ、Main technical specification

1、Accuracy Class：0.5%F·S±1B
2、Display Digit：4
3、Reference Input：AC /AV：0～5A/0～500V  volts D.C.：0～199.9V  0～1000V
4、Power consumption：≤3W
5、Working power：AC85～242V，50/60HZ
6、Working circumstance：0～50℃，relative humidity≤85％，without corrode and electric radiation

Ⅲ、Panel board and connection

1、Panel board

The panel board function of each model can follow the above drawing.

2、connection

Ⅳ、Operation

1、Interior parameter(onlyCurrent、Voltage model meter have this parameter)

2、Operational flowchart：

3、connect according to the connection, the instrument will test by itselffor 1S.

4、Interior parameter setting（parameter definition refer to parameter sheet）Press SET key for 3S to enter theInterior parameter setting state，it displayparameter code first，and then display parameter value after 2s，press▲、▼to modifyparameter value，and press SET to save and enter the next parameter setting ,exit tillthe setting finished. If not press any key ,it will save and exit automatically.

5、★current、voltage mode：if the meter display has warp，you can press ‘SET’&▲&▼key at one time toclear.（please be cautiousto use this function）.
