(1) Error code
The error code display is only shown when an error exists. Each digit
stands for a reason for the error according to the table on page 4. Sever-
al errors can occur at the same time.
If a leak has been detected in the system, the letter sequence "LEAC"
is displayed. The display goes off automatically as soon as the leak has
been eliminated.
(2) Error date
The display only appears if there is a serious functional problem. The
date is shown on which the meter's functional problem occurred. If a
serious error occurs, the error date indicates the time at which the con-
sumer displays were "frozen".
The arrow on the display shows the respective direction of fl ow.
(Arrow to the right - positive fl ow, arrow to the left - negative fl ow)

(3) Cumulated volume
The cumulated volume is displayed in m
3
with three decimal places.
This example shows 1823 litres.
(4) Segment test
This display should ensure that all display segments work perfectly.
All the segments appear on the display for 0.5 seconds, and the
complete display goes dark for a further 0.5 seconds.
Then the display jumps to the next display step.
(5) Last due date
This display “
Last due date
” shows the date on which the cumulated
volume was saved. (Date of the last due date)
The display “
Not yet reached
” shows the date without the year number
because the date of the key date has not yet been reached.

(6) Consumption on last due date
This display shows the cumulated volume on the last due date.
If the fi rst due date has not been reached yet, "0.000" appears on the
display.
(7) Checksum
The checksum is formed from the cumulated volume on the last due
date, the date of the due date and the device number.
This display can be used for later checks on the readout values (e.g. for
postcard readouts).
(8) Radio mode
This display shows which radio mode the device is operated in.
