FLUXUS F808, F809 13 Data logger and transmission of data
124 UMFLUXUS_F808_8091V1-2-1EN, 2019-08-23
13.1.3 Settings of the data logger
Select program branch Special Funct.\SYSTEM settings\Storing. It contains the following menu items:
• start of the storing
• ringbuffer
• storage mode
• storing of the totalizers
• storing of the signal amplitude
• storing of the fluid sound speed
• storing of the diagnostic values
Start of the storing
If it is necessary to synchronize the storing of measured values on several transmitters, the starting time of the storing can
be set.
Ringbuffer
The setting of the ringbuffer influences the storing of measured values as soon as the data memory is full:
• If the ringbuffer is activated, the available data logger will be halved. The oldest measured values will be overwritten.
Only the data logger capacity that was free during the activation will be used by the ringbuffer. If more data logger capac-
ity is necessary, the measured values in the data logger should previously be deleted.
• If the ringbuffer is deactivated, the storing of measured values will be stopped.
Storage mode
Storing of the totalizers
see section 12.3
Select the starting time of the storing of measured values.
Promptly: Storing will be started immediately.
On full 5 min.: Storing will be started on the next full 5 minutes.
On full 10 min.: Storing will be started on the next full 10 minutes.
On quarter hour: Storing will be started on the next full 15 minutes.
On half hour: Storing will be started on the next full 30 minutes.
On full hour: Storing will be started on the next full hour.
example: current time: 9:06 o'clock
setting: On full 10 min.
Storing will be started at 9:10 o'clock.
Select the behavior of the ringbuffer. Press ENTER.
Select the storage mode. Press ENTER.
If sample is selected, the displayed measured value will be used for storing and online
transmission of data.
If average is selected, the average of all undamped values measured during a storage in-
terval will be used for storing and online transmission of data.
Note! The storage mode does not affect the outputs.
Note! Storage mode = average
The average of the selected physical quantity and other physical quantities assigned to the measur-
ing channel will be calculated.
If the storage rate < 5 s (see section 13.1.2) is selected, sample will be used.
If no average could be calculated over the complete storage interval, the value will be marked as in-
valid. The ASCII file of the stored measurement data will contain (???) for invalid average values of
the measured value.
