Applications

MPR-4 Series devices are microprocessor-based devices which are designed to measure all parameters

of an electrical network, calculate the consumption values and display these on its LCD screen.

Measured parameters will be recorded in real-time thanks to internal flash memory and Real Time Clock

chip. These recorded values then can be accessed and monitored remotely via RS-485 line with Modbus

RTU protocol. Ethernet feature can be used instead of RS-485.

Button Functions

In addition to their main functions, the 5 buttons on the front panel can be used as shortcut buttons for

easily reaching screens.

ESC button (9): It has 3 main functions:

Exiting from any menu is done by pressing ESC button.

While on measuring screen: As seen on the symbols (V I F) above the button, it is used to

browse between voltage, current and frequency measurement screens.

While on measuring screen: As seen on the symbols (Event) below the button, event screen is

reached when pressed for 3 seconds.

BACK Button (10) : It has 3 main functions:

While on measuring screen: As seen on the symbols (P PF) above the button, it is used to

browse between active power, reactive power, apparent power, power factor and Cos φ

measurement screens.

It is used to select the previous digit while entering a numerical value in the menu or to browse

back to a previous menu level.

While on measuring screen: As seen on the symbols (Test) below the button, connection control

is reached when pressed for 3 seconds.

Down Button (11) : It has 2 main functions:

While on measuring screen: As seen on the symbols (E Clock) above the button, it is used to

browse between import/export active energy consumption, reactive energy consumption, tariff

and time information screens.

While on menu screens: It is used to browse between menu options and to decrease a value

during adjustment.

Up Button (12) : It has 2 main functions:

While on measuring screen: As seen on the symbols (THD H) above the button, it is used to

browse between THDV, THDI and individual harmonic measurement screens.

While on menu screens: It is used to browse between menu options and to increase a value

during adjustment.

SET Button (13) : It has 3 main functions:

It provides access to menu screens when pressed for 3 seconds. When the PIN is active, a

password is asked before entering the menu. After the correct password is entered, access

to menu is allowed.

It is used to reach the desired adjustment screen and to save the changed settings. Pressing the

button is enough for this operation.

While on measuring screen: It is used to browse between Min, Max, Demand and Max Demand

screens.
