DESCRIPTION OF THE DEVICE
The three-phase energy meters 7M.38.8.400.xxxx are intended for energy measurements in three-phase electrical power
network and can be used in residential, industrial and utility applications. Meters measure energy directly in 3-wire and
4-wire networks according to the principle of fast sampling of voltage and current signals.
A built-in microprocessor calculates active/reactive/apparent power and energy, current, voltage, frequency, power factor,
power angle and frequency (for each phase and total sum) from the measured signals. This smart meter can also perform
basic harmonic analysis (THDU, THDI). This enables quick overview of harmonic distortion either coming from a network
or generated by the load. Microprocessor also controls LCD, LED, IR communication and optional extensions.
A capacitive touch button on the front of the energy meter enables access to switch between measurements and settings
in the menu. Connecting terminals can be sealed up against non-authorised access with protection covers.
The meters are built to be fastened according to EN 60715 standard.

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 nd 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 specic segment of the menu
and for conrming the settings. Press the capacitive touch (short-touch) to move forward between the screens. Long-touch
(approximately 3 seconds) is used to conrm 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 o, the rst 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.

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 specic 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 dened 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 verication.
After power o meter automatically goes back to normal operation.
User’s Manual 7M 15
CAPACITIVE TOUCH SELF CALIBRATION PROCESS
In a reported xed 64s interval the average, minimum and maximum value of the capacitive touch sensor is calculated.
If the conditions are stable (without interruptions) then the average value of the capacitive touch sensor is used as a reference
value.
If the new reference value deviates suciently from the permanently stored value, it is permanently saved.
Permanently stored value is used when the power is turned on.
ENERGY COUNTERS
There are two sets of energy registers – four non-resettable registers which can be assigned for active energy (MID approved),
reactive energy (national approval) or apparent energy (no approval).
The meter with MID approval should have at least one register with active energy measurement.
There are additional 16 energy registers which can be parameterised by the user regarding type of energy, active quadrants,
direction of counting and tari and they can also be resetted using MODBUS command or cap touch.
On the LCD up to two energy counters are displayed.
There is the lock sign for the xed legally relevant non-resettable counters, the counter designation, the sign of currently
active register, an additional code and the unit.
For the code the user can choose between the OBIS code or letter description code (the latter is the default). The 9-digit
numerical number shows the value of the energy. The decimal dot is xed and resolution is xed to 100 Wh. The screen is
displayed for the pre-set cyclic period.
PLEASE NOTE
In compliance with the MID directive, where the nal test is done before selling the products, it may happen that the MID
energy meters show a low energy consumption even if they are new.
This can only happen to relatively small percentage of meters for each production lot and the highest value should be
around 6 kWh for the Active Imported Energy

single-phase measurement in L3 (L+N) and 3-system 3–wire connection (3L) with import
– export evaluation as the sum of phases.
Also this connection has to be conrmed to block further changes and after conrmation
the message Installation not set is switched o.
In case 4-wire arithmetic mode with import-export evaluation for individual phases or 3-wire 2-system connection are chosen
the password DCBA has to be entered to allow the modication. In 3L-2I connection the phase measurements are blocked
on LCD while in 3L connection they are not automaticly blocked.
It is recommended to remove phase voltage and power measurements at Displayed measurement setting as these are not
relevant at 3-wire connection.
User’s Manual 7M 26
ERROR DISPLAY ON LCD
If error is detected Error display appears on LCD after each cycle for 5 seconds.
The rst two bits are the summary description of CRC errors.
The decimal value of rst 3 Bits (0 ...7) is displayed as Error.
The other bits are shown with 2 values:
- Data CRC – shows Parameter CRC details – decimal value (0...3f) of bits 8 to 13
- Code CRC – shows Firmware CRC details – decimal value (0 ...1f) of bits 3 to 7
CALIBRATION AND SETTING PARAMETERS
Calibration parameters can only be changed in production.
They cannot be changed by upgrade or dierent processes.
Special factory software is used to calibrate the parameters for current, voltage, and phase angle.
If these parameters were tenaciously or accidentally changed, an error type 1 is detected and Error 1 is shown on the LCD.
Calibration parameters are checked every 64 seconds.
The parameters related to energy measurement can only be changed if the MID key is unlocked.

APPENDICES
APPENDIX A: MODBUS - COMMUNICATION PROTOCOL
Modbus protocol enables operation of device on Modbus networks. For 7M.38.8.400.XXXX\ with serial communication the
Modbus protocol enables multi drop communication via RS485 communication. Modbus protocol is a widely supported
open interconnect originally designed by Modicon.
The memory reference for input and holding registers is 30000 and 40000 respectively.
PLEASE NOTE
The Modbus table is subject to change without notice.
For the latest and complete Modbus table please visit FINDER S.p.A web page.
Communication operates on a master-slave basis where only one device (the master) can initiate transactions called ‘Requests’.
The other devices (slaves) respond by supplying the requested data to the master. This is called the ‘Request - Response Cycle’.
The master could send the MODBUS request to the slaves in two modes:
• Unicast mode, where the master sends the request to an individual slave. It returns a replay to the master after the request
is received and processed. A MODBUS transaction consists of two messages. Each slave should have an unique address.
• Broadcast mode, where the master sends a request to all slaves and an answer is never followed. All devices should accept
the broadcast request function. The Modbus address 0 is reserved to identify the broadcast request.
MASTER TO SLAVE REQUEST
SLAVE TO MASTER RESPONSE
REQUEST
This Master to Slave transaction takes the form:
• Device address: master addressing a slave (Address 0 is used for the broadcast address, which all slave devices recognize)
• Function code e.g. 03 asks the slave to read its registers and respond with their contents
• : tells the slave which register to start at and how many registers to readData bytes
RESPONSE
This Slave to Master transaction takes the form:
• : to let the master know which slave is respondingDevice address
• Function code: this is an echo of the request function code
• : contains the data collected from the slaveData bytes
