Storage rate
If a starting time for storing the measured values is defined, a storage rate has to be entered. The storage rate indicates
the interval how often the measured values are transmitted or stored.
• Select the menu item Storage rate.
• Press ENTER.
• Select a storage rate from the scroll list.
• Press ENTER.
• If Customized is selected, enter the storage rate.
• Press ENTER.
Ringbuffer
The data logger can be configured as linear logger or ringbuffer. If the ringbuffer is deactivated and the data logger is full,
the storing of measured values will be terminated. It can be continued after clearing the data logger. If the ringbuffer is
activated and the data logger is full, the oldest measured values will be overwritten. In ringbuffer mode, the remaining
capacity of the data logger is displayed during the measurement, e.g.:
Log←→ : 1d 6h 57m is displayed, if no measured values have been overwritten.
Log|←→| : 1d 6h 57m is displayed, if the old measured values have been overwritten.
• Select the menu item Configuration.
• Press ENTER until the menu item Ringbuffer is displayed.
• Select On to activate the ringbuffer.
• Press ENTER.
If the ringbuffer is deactivated and the data logger is full, the storing of measured values will be terminated.
• Select Off to deactivate the ringbuffer.
• Press ENTER.
Storage mode
• Select the menu item Storage mode.
• Press ENTER.
• Select Sample to store the current measured value.
• Select Average if the average of all undamped measured values of a storage interval is to be stored.

Notice!
Storage mode = Average
The average of the physical quantity and of other quantities (e.g., the measured temperature) will be calculated.
If a storage rate < 5 s is selected, Sample will be used.
If no average could be calculated over the complete storage interval, the value will be marked as invalid.
