7.7 Clearing the logger memory
The query to clear the logger memory always appears after the data from the
logger have been read in to the database. If the logger memory is not cleared
after the data has been read in, the query to clear the data reappears during
the setting up of a new logging job. At this point of time the logger memory
has to be cleared so the logging job can be set up.
You can also clear the logger memory manually.
Note
There is no danger of clearing data that have not been read in as the data
stored in the logger have to be read in (compulsory guide) when the logger is
connected. If data stored in the logger are not read in, the logger cannot be
connected to the PC program.
Proceed as follows to clear the logger memory:
1 In the Device menu, select the menu item, Memory/Clear memory.
2 A security prompt appears. Confirm the security prompt with OK.
3 The data is cleared. A message appears after the clearing that
informs you that the memory was cleared. Confirm the message with
OK.
