Do not clear logger This is the default setting if the logger memory is
not yet full.
Use this setting when the logger memory is not yet
full and all you want to do is change Stop mode set-
tings without clearing the existing samples.
If the logger memory is full, or if Start mode or
Sample Interval changes are required, you must
use the Clear logger setting to make the necessary
changes.
Clear Logger This is the default setting if the logger memory is
full.
The Clear logger setting allows you to modify
both Start and Stop mode parameters and change
Sample Interval values. Choosing this setting re-
sults in the logger’s memory being cleared follow-
ing completion of the setup changes. You will lose
data unless you transfer it first.
If you are in doubt as to whether the information on
the logger is still valuable, first make a copy of the
data using Logger>Transfer, and then make the
necessary logger setup changes.
When you choose Clear logger, the Start Mode
and Stop Mode radio buttons become available.
