Programme operation

In programme status, digital interface adopt layers structure menu type, meter supply three lines number display (se fig. 5)
No.1 line is first layer menu information;
No.2 line is second layer menu information;
No.3 line is third layer menu information;
Exp: The fig.5 shown: No.1 layer: INPT = Signal input; No.2 layer: CT = current transformer; No.3 layer: current value is 5, It means ratio of CT is 25/5A.
The digital display interface menu has the following organizational structure, the user can choose the appropriate setting parameters according tho the actual situation.

Digital output Set DO- i (i is 1 ∼ 4)| Choose alarm item or close alarm| Set alarm item’s specific threshold value| Choose alarm item, and set relative threshold value (when alarm item is digital value, no need set threshold value), once meet alarm condition, switch output working
---|---|---|---
Analog output Set
AO—i (i is 1 ∼ 4)| Chosen transmitter item or close analog output (refer to 8.2 analog output)| Set the full scale value of analog item| Choose transmitter item’s and relative electrical parameter (0-20mA, 4-20mA, 4-12-20mA) For example, set “A0-1″ TYPE”0135″ UAL”5000”, which means A phase current 0-5A corresponds to the transmitter output signal of first loop 4-20mA

Note: The above menu is applied to the product with complete functions. If you find there is no such menu in the product or the menu is not working, It means the product not supporting the function.
