As mentioned above the first four fields with the figures 0-3 indicate whether the info codes are active, and it
thus appears that LEAK and BURST are currently active.
The binary values of the remaining fields must now be converted into decimal values, which indicate how long the
corresponding info code has been active within the latest 31 days according to the above table. It appears that
BURST has been active for 1-8 hours and LEAK has been active for between 15 and 21 days. Furthermore, DRY has
been active for 2-3 days within the latest 31 days.

displays.
Furthermore, the two square ‘dots’ at the bottom right of
the display shift every second.
The flow is measured every four seconds and new values (flow, volume, etc.) are calculated every 32 seconds.

Verification mode
Verification mode is meant for verification of the meter.
In the display, verification mode will be indicated by the volume unit symbol ‘L’
. In addition, the 2 dots at the
bottom right of the display are changing twice per second.The flow is measured twice per second and new values
(flow, volume, etc.) are calculated every four seconds.
When the meter switches to ‘verification mode’, the wireless M
-Bus radio transmitter will be turned off. At the
same time a time-out starts. When the time-out period has expired the meter switches back to normal mode.
The time-out period is 9 hours.
