Error code | Leak detection | Error date
(1) Error code
EN
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.
Several 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 a serious functional problem has occurred.
The date on which the meter's functional problem occurred is shown. 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)

Cum. volume | Segment test | Last due date
(3) cumulated volume
EN
The cumulated volume is displayed in m
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
The 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 year, because the
date of the due date has not been reached.

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.
