If no parameter is changed, the internal date / time on the pressure gauge is not modified.
During the date / time update, the seconds are automatically set to zero.
The DataLogger allows the storage of up to 130,000 (65,000 if the temperature is also stored) measurement
points in steps ranging from 1s to 10 hours according to the parameter t1 defined in the Parameter Menu. The
duration of the cycle is established by the parameter t2 always defined in the Parameter menu.
Each reading cycle can be stopped before the set time and restarted with the same settings up to four times,
or it is possible to repeat the last performed cycle once again up to four times. Once the limits is reached, it is
no longer possible to continue and a new cycle must be started with consequent loss of the recorded data. If,
during the repetition of the cycle, the maximum recording capacity is reached, the cycle stops.
WARNING! The initialization of a new cycle causes the loss of previously stored data.
For very long Datalog cycles it is possible to save on battery consumption by using the stand-by function of the
pressure gauge.
This feature is activated automatically when the acquisition time between 2 storage points is greater than the
Auto Power Off time.
Example:
Auto Power Off Time: 1 minute
Acquisition time (t1): 5 minutes
In these conditions, in the interval between the two acquisitions, the pressure gauge switches off the display
and deactivates the other functions. It is reactivated 30 seconds seconds before making a measurement and
for the next 5 seconds.
In any case, during a datalog cycle, the auto switch off function of the pressure gauge is not active.
If an excessively low battery level is detected, the datalog cycle will automatically stop. All data stored
up to that point are saved in the internal memory.
For particularly long datalog cycles, the internal battery on the pressure gauge is not sufficient. The
pressure gauge must be powered externally through the USB port.
Note:
The functionality of the DataLogger is fully manageable by PC using the Quick Analyzer software through which
it is possible to:
