Measurement
Voltage
This screen shows the phase-neutral voltage values for each phase. You can see Min Voltage
(Phase-Neutral) and Max Voltage (Phase-Neutral) values by pressing the OK button. Depending on
the connection type in the Phase-Neutral voltage (3P3W, 3P3W balance and Aron), this screen will
not be displayed.
This screen shows the phase-phase voltage values for each phase. You can see Min Voltage (Phase-
Phase) and Max Voltage (Phase-Phase) values by pressing the OK button.
11
Current
Instantly measured current values for each phase are displayed on this screen. You can see Min
Voltage (Phase-Neutral), Max Current (Phase-Neutral), Demand (Phase-Neutral) and Max Demand
(Phase-Neutral) values by pressing the OK button.
Neutral Current
This screen shows the calculated neutral current value. You can see the Min and Max values by
pressing the OK button. Also depending on the connection type of the neutral current screen (3P3W,
3P3W balance and Aron), this screen will not appear.
12
Frequency
You can see the operating frequency of the device on this screen.
Cos Phi
You can see cos phi values of each phase separately on this screen.
Total Cos Phi
You can see total cos phi values on this screen.
13
Total Run Hour
It is the screen on which the run hour of this device is displayed. You can view the time it has worked
since the rst power-up on the screen. The value on the screen increases by 1 in 3.6 seconds. If you
multiply the value on the screen by 3.6, you can reach the total operating time.
Run Hour
This screen works according to the condition of the parameters selected from the settings. It is the
counter that will run when the parameters exceed the threshold value entered by the user. The value
on the screen increases by 1 in 3.6 seconds. If you multiply the value on the screen by 3.6, you can
reach the total operating time.
Parameters (Depends on device)

Settings
Press and hold OK to access the settings menu. If you wish to do something under the Settings
menu or change the settings, press OK to go to menu details and change Product or User settings
under the Settings menu. In the Settings menu, the symbols in the right corner of the screen indicate
which setting you are in.
User Settings
It is the menu where you can set the Language for your device. You can use the up and down arrow
buttons to choose between Turkish, English, German and French.
Security Settings
You can activate and deactivate the password protection with the arrow button in the safety setting.
You should select one of the options: Yes/No. If Yes is selected, the password screen will be
displayed each time you change the setting. If No is selected, the password screen will not appear.
15
Password Setting
On this screen, you can set the password that you will use for the security of the device. The current
password is entered on the rst screen.
If it is entered correctly, the screen for entering the new password will be displayed. The screen for
re-entering the password is displayed to conrm the new password. As with all settings, the saving
conrmation must be set to yes when exiting the settings for the new password to be active.
Connection Settings
In this screen, you can scroll with the arrow and congure the connection settings.

Voltage Transformer Setting
In this screen, you can congure the voltage transformer settings. If you are using a voltage
transformer, you must set the setting to on and then enter the primary and secondary values.
19
Current Transformer Setting
It is the menu in which the primary and secondary values for the current transformer are entered. You
will be prompted to enter CT Primary and CT Secondary values respectively.
Communication Settings
Communication and Modbus RTU settings of the device are made in this menu. Modbus address, bit
rate, parity bit settings of the device are made in this menu (For models without communication, this
screen will not be available).
20
Modbus Address: This parameter can be set to a value between 1 and 247. The value set must be
unique on the line where the product is found. Otherwise, communication of the line, to which the
product is connected, will be disrupted.
Bit Rate: This parameter can be set to one of the following values: 2400, 4800, 9600, 19200, 38400,
57600, 115200 or 256000 bps. The value of this parameter must be the same as the value in the
software you use to communicate with the product. Otherwise, you cannot communicate with the
product.
Parity Bit: The parity bit can be set to N/A, single or double. The value of this parameter must be the
same as the value in the software you use to communicate with the product. Otherwise, you cannot
communicate with the product.
