General Informations

The device can be used in electrical panels, laboratories and test devices. With

the assistance of a current transformer, it measures the AC current passing

through the system in terms of Amper unite. After energizing the device,

“dA -A “ message appears on it's screen for 2 seconds and then it starts to

show the current value

■ The current transformer ratio can be adjusted between 5/5 and 10000/5 using

the touch buttons on the front panel of the device.

■ Stores the maximum demand value and the peak value on its memory and

keeps these values even if the energy supply goes off.

■ When the measured value of the seconder current reaches 5,1 A, “ OvEr”

message starts to flash on the screen to warn the user that the value of the

current exceeded the limit values.

Button Functions:

Using the direction buttons, it is possible to go through the nemu up and down.

“SEt” message will appear on the screen if the set button pressed. To set one

of the parameters set button must be pressed again inorder to enter that menu.

The first parameter that can be set in the set menu is transformer's primer

current value, that would flash on the screen with the message “ CtrF” while

setting. Pressing the set button and the direction buttons can increase and

decrease this value “ between 5 and 10000”. after reaching the required value

set button should be pressed to store this value on the device. After that

pressing the down button leads to the demand time setting with dd-t flashing on

the screen.

To make an adjustment, set button must be pushed. With the direction buttons

the value can be adjusted “between 10 and 60 minutes”. After reaching the

required value pressing set button would store this value. Next what would

appear in the SEt menu pressing the down direction button is qUit. Pressing the

set button would exit the set menu.

The next menu after set menu is Clr, “ can be reached by pressing down button”.

To clear the maximum demand and the peak value set button must be pressed.

After the Clr menu qUit show appear. Pressing set there would return the

screen to the measurement screen.

While in measurement screen, pressing the up direction button shows the

maximum peak current value occurred since the last operation done, pressing

the down direction button shows the maximum demand occurred since last Clr

operation done.
