During power-up, the type and firmware version of the meter is displayed
for 10 seconds.
The display contains:

In the main field, "100" and the characters to define whether it is an
active or a combimeter respectively a meter with or without supply
control switch, e.g. 100 Ab, 100 AC, 100 bC, 100 bb.

In the index field, the firmware version,
e.g. 21 for version M21 or with alternative format: 2300 for M23.0.0.
Firmware version M26 and upwards:
Depending on the execution, a checksum describing the exact firmware
version is shown in addition or instead of the firmware version.
Then the service display appears for the parameterised start-up time. If the
start-up time for the service display is zero, the display starts directly with
the main display.
The service display allows tests to be carried out by allowing registers to be
displayed at higher resolutions. It provides information to assist the installer
during installation or during subsequent testing of the network status. The
service display may also include data, which can give information about the
state of the meter during work in the field or in the test facility.
The service display may be accessed

when the meter is first powered up,

on a long press (more than 5 seconds) of the display button in the
main display, or

when the terminal cover is removed.
Exception: If the display button is pressed for a long time while the
consumption since last reset is displayed, the register is reset instead.
The way in which the service display is accessed is determined by
parameterisation.
The items on the service display (maximum 63) can be scrolled through
with short presses (less than 5 seconds) of the display button.
The meter exits the display list when either

the end of the service list is reached.

the terminal cover is replaced, or

a defined time after power-up has expired [configurable between 1 and
255 minutes].
Removal of the terminal cover will override all of the above and the meter
will not exit service mode until the terminal cover is replaced .
