User Interface 

The EMM5 user interface uses a combination of a graphical LC display with automatic backlight and four multi-function 

softkeys. The action, a key performs, depends on the actual context and is given by small icons at the bottom of the 

display. This means a much more easy and intuitive usage of the device, even in complex situations. 

After the supply voltage is connected to the device, it will take a short time to power up and initialise itself. During this 

time, the display remains empty. After the power-up-procedures have been completed, an entry-screen is displayed. 

The keys on the left and the right (icon is a capital “M”) will proceed to main menu. 

 

If, after waiting for some seconds of set-up-time, the display does not show the introduction screen or 

is fully dark, it is possible that the display contrast is not set properly. The user would not be able to 

navigate to the display contrast set-up menu in this case, so an additional possibility to set the contrast 

is included in the introduction screen: press one of the two keys in the middle repeatedly to change contrast. If no 

change can be seen, try the other key. The value is automatically saved for the next start.

Main menu 

The main menu is the central point of the device's menu navigation. It shows the following items: 

 

MEASUREMENT: This submenu contains the measured values 

 

AUTO-ROLL: Measurement display with automatic switching to the next value 

 

HARMONICS: This submenu shows the single harmonics for the input channels (voltages L1-N, L2-N, L3-N and 

currents I-1, I-2, I-3, I-N) 

 

WORK: This submenu contains the work counters  

 

SETUP: The device setup can be found inside this menu 

 

DEVICE INFO: This submenu displays some information about the device 

 

EVENTRECORDER: Contains all stored alarm including timestamp and grid data. (The event recorder is available 

in devices with the option –DM only) 

KEYS: 

The user can navigate through the menu entries by use of the "

 "and "

” keys. On the top left side a tiny arrow shows 

which item is actually selected. By pressing "

", one can enter the selected submenu.
