FIRST STEPS
Programming a three-phase electrical energy meter 7M.38.8.400.xxxx is very transparent and user friendly.
Numerous settings are organized in groups according to their functionality.
In this chapter you will find basic programming steps:
- KEYBOARD NAVIGATION
- LCD USER INTERFACE
- CALIBRATION AND SETTING PARAMETERS
- FREEZE COUNTERS
KEYBOARD NAVIGATION
The capacitive touch (symbol below) is used for shifting between screens, for selecting the specific segment of the menu
and for confirming the settings. Press the capacitive touch (short-touch) to move forward between the screens. Long-touch
(approximately 3 seconds) is used to confirm the selection, to sett the next digit, or to enter the sub-menu. Very-long-touch
(approximately 5 seconds) considers the function ESC (during the parameter setting the screen goes back to the explicit
parameter in the other cases the LCD returns in the initial cycling mode).
If the screen backlight is off, the first touch turns on the backlight, then the long-touch to view the main menu.
If the lock of the capacitive touch is available, to activate it, a very long-touch is needed.

SN: serial number
MID: Version and CRC of Part 2
FUN: Version and CRC of Part 2
HW: Hardware version; m.: CRC of phase measuring modules (high, low)
Run: Operational time (days hours minutes)
After the electrical connection, the display shows an info screen (picture on top) for two seconds.
The following is holding page (default setting) of last observed measurement on the screen.
Measurements consist of energy counters and other actual measured values.
The MID approved meter shows a warning screen (picture on the right) Installation
Not set every 5 seconds if the installation of connection mode is not set yet.
Besides the holding page of measurement, one can enter the display menu structure by using a long touch. If the capacitive
touch is not pressed for more than 90 seconds, that specific measurement screen will be shown again.
This is also in case of a powerdown.
Cycling page function is a function that cycles measurements on the screen regarding the period that is defined in settings
(for more details see chapter Settings, Device settings, General settings, Display). If the capacitive touch is not pressed for
more than 90 seconds, the cycling of measurements automatically begines again. The explicit settings can be changed
through the Setting menu (for more details see chapter Display of device setting), Fi-MIS software or mobile app using NFC.
PLEASE NOTE
All settings that are performed can be subsequently changed via Fi-MIS by means of communication
PLEASE NOTE
The meter can be set to Test measuring mode which displays energy registers with better resolution.
The test mode is used for test purposes during type testing and test of meter constant during initial verification.
After power off meter automatically goes back to normal operation.
