Operation Mode (RUN)
This menu is a display menu for standard operation mode. Containing the follow-
ing sub menus, it is not required for parameter setting:
Fig. 8-3
Operation mode selection
Normal
Display (basic screen) with information about the name of measurement place,
time, medium temperature, flow quantity, average velocity and total volume.
If the transmitter is disconnected from mains at the time of totalising set, it is
not possible to create or to save a total for the respective day.
If the unit has been shut down temporarily between two totalising points, the
flow rate missed during the inoperative period is not going to be considered for
totalising. There will be no averaging interpolated replacing the lost flow rate!
Trend
Operates like an electronic writer. Average cycle values of level and average
flow velocity will be recorded for the past 90 days. Values can be individually
selected and viewed in a submenu.

Trend value selection
The period within which values have been averaged is indicated on the bottom
line of the graphic display. New values will be added as vertical lines on the
right-hand side each time after the programmed storage interval has expired
(see Fig. 8-5). This is why the oldest value moves to the left-hand side of the
display and from there into the internal memory area.
By using the arrow keys >left< and >right< you can scroll within the time axis in
order to view older data sets. Browse through day values (steps of 24 hours) us-
ing the arrow keys >up< and >down<. This enables to determine and to evaluate
previous measurements, trends, dry weather periods as well as possible meas-
urement problems which have been occurred some days before.
