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 two dots at
the bottom right of the display are changing twice per second.
The flow is measured twice a 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 turns 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.
