Monthly memory
Monthly memory contains the history of the events for the last 18 months. The monthly memory
is implemented as a shift register. The current monthly data is transferred on the parameterized
monthly set day
. The data for the oldest previous month are then lost.
The data in the monthly memory are stored without a time stamp. The memory only indicates
whether an error occurred in the month in question or a certain event occurred. No information
is given, for example, about the duration of the error condition.

In
normal mode
, flowrate measurement and temperature measurement are performed in a
timebase (
measuring interval
) of 4 seconds (parameterizable: 0.5 / 1 / 2 / 4 or 8 seconds) or
30 seconds (parameterizable: 2 / 4 / 8 / 30 / 60 seconds).
If
power saving mode
(“
saving mode
”) has been parameterized – and the calibration seal is set
– the LCD is only activated once every 5 seconds for approx. 0.5 seconds after 15 minutes of
inactivity (no LCD button is pressed and no data traffic). This mode is exited when an LCD
button is pressed and the LCD then permanently displays. After another 15 minutes of inactivity
(no LCD button pressed and no data traffic through the optical interface), the LCD again
switches to “power saving mode”.
Caution: If the service button is pressed in this state, display mode remains!
