Log functions
Logbook
In the internal logbook, metrologically relevant
events (errors, states, actions) are stored in
chronological order with their time of occurrence.
The events acquired are predefined. The data of the
logbook cannot be deleted.
Each event is stored in a separate 4-level shift
register; the overflows are transferred to a 25-level
circulating buffer. Therefore, at least the last 4 times
can be traced for each event.
In a monthly register, the error states are stored for
the current month and for the past 18 months
(without time stamp).

Type Description
1 F0 = Air in measuring tube
2 F1 = Interruption flow sensor
3 F2 = Interruption return sensor
4 F3 = Error temperature electronics
5 F5 = Short-circuit flow sensor
6 F6 = Short-circuit return sensor
7 F8 = Sensor error > 8 hours
8
Error occurs or back-to normal
F9 = ASIC error

Read-out is performed via the optical interface with
the service software.
Data logger
(optional)
The data logger permits the archiving of data that the
user can select from a predefined set of values. The
data logger contains four archives whose 8 channels
can be assigned.
The data can be assigned to any of the channels.

*) For a shorter measuring period than 1 hour, the
largest value from the maximum values calculated
within one hour applies.
The data are recorded with the value and time
stamp.
Parameterizing and read-out is performed via the
optical interface with the service software .
Note: Data transmission is in a manufacturer-specific
format.
