13.1.3 Data logger settings
Select Special Funct.\SYSTEM settings\Storing. It contains the following menu items:
• start of storing
• ringbuffer
• storage mode
• totalizer storing
• signal amplitude storing
• storing of the fluid sound speed
• diagnostic values storing
• acoustic signal during storing
Start of storing
In order to start the storing of measured values with several measuring instruments at the same time, it is possible to set a
starting time.
Ringbuffer
The setting of the ringbuffer influences the storing of measured values as soon as the data logger 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 memory that was free during the activation will be used by the ringbuffer. If more data logger mem-
ory is necessary, 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
Totalizer storing
see section 12.2
Select the moment at which the storing has to start.
Promptly: The storing starts immediately.
On full 5 min.: The storing starts in the next full 5 minutes.
On full 10 min.: The storing starts in the next full 10 minutes.
On quarter hour: The storing starts in the next full 15 minutes.
On half hour: The storing starts in the next 30 minutes.
On full hour: The storing starts in the next full hour.
Example: actual time: 09:06 am
setting: On full 10 min.
The storing starts at 09:10 am.
Select the behavior of the ringbuffer. Press ENTER.
Select the storage mode. Press ENTER.
If sample is selected, the current measured value will be used for the storing and online
transmission of data.
If average is selected, the average of all values measured during a storage interval will be
used for the storing and online transmission of data.
Note! The storage mode does not affect the outputs.
Note! Storage mode = average
The average of the physical quantity and other physical quantities assigned to the measuring chan-
nel, e.g., the measured temperature, will be calculated.
If the storage rate < 5 s (see section 13.1.2) is selected, the 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 will contain ??? for invalid average values of the measured values and
?UNDEF instead of invalid temperatures.
