For general use, the following diagram is provided, which allows the total recording time to be estimated based on the number of
variables used. A sampling interval of 300s is assumed.

Fig. 1: Total recording time according to the number of
variables (sampling interval 300s)
To determine the total sampling time, the following points should also be considered:
The areas of memory reserved for the three types of variables are separate, and thus the total recording times are different for
each of these. In any case, the free space returned is the lesser of the three.
Modification during the operation of the instrument of parameters that affect the operation of the logs, such as the current time or
the sampling time, may decrease the total recording time remaining.

Request free space:
The free space remaining in the logs can be called as follows :
From the main screen, press the button “
Ã
” repeatedly until the “info” screen appears
Choose “Logs”. The screen “Variable log - free space” will be displayed, indicating the percentage of space remaining.
This value is automatically shown as “100%” when the data is downloaded by the service centre, printed completely, or
alternatively by the user from the setup->maintenance menu.
Deleting the logs:
To delete all the logs:
From the main screen, press the “prg” button for three seconds and enter the configuration password
Choose “Maintenance” and then “Delete Variables log”. Confirm when requested.
(Note: the delete process may take a few minutes).

The configuration of the controlled variables is handled by the
3ODQW:DWFK0DQDJHU
program. For the use of this program please
refer to the corresponding manual.
NOTE: changing the configuration of the variables or the number and type of instruments configured will delete all the
previously saved data logs.
