Ⅰ、Survey：

D series intellective electric meter（Digital Ammeter、Digital Voltmeter、Frequency Meter、Tachometer and so on）is a type of multifunctional composite type meter, it apply to electric power and electric network, field monitoring and display of automatic control systems and remote control and measurement of automatic dispatch telemechanical device，its function is to output  standard current or voltage transfer signal using CPU operation electric network’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 RS485 communication 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(only Current、Voltage model meter have this parameter)

2、Operational flowchart：

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

4、Interior parameter setting（parameter definition refer to parameter sheet）

Press SET key for 3S to enter the Interior parameter setting state，it display parameter code first，and then display parameter value after 2s，press▲、▼ to modify parameter value，and press SET to save and enter the next parameter setting ,exit till the 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 to clear.（please be cautious to use this function）.
