14.1.3 Settings for the Data Logger
Select Special Funct.\SYSTEM settings\Storing. It contains the following menu items:
• Start of Storing
• ringbuffer
• storage mode
• storing of the totalizers
• storing of the signal amplitude
• storing of the sound speed of the fluid
• storing of the diagnostic values
• acoustic signal during the storing
Start of Storing
In order to start storing of measured values with several measuring instruments at the same time it is possible to set a
starting time.
Ringbuffer
Setting the ringbuffer influences the storing of measured values once 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
Storing of the Totalizers
See section 13.3.
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 displayed measured value will be used for storing and online
transmission of data.
If average is selected, the average of all values mea-sured during a storage interval 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 physical quantity and other physical quantities assigned to the measuring chan-
nel, will be calculated.
If the storage rate < 5 s (see section 14.1.2) 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 value.
