Clear All Data.
You can clear all data from the datalog. The QRAE II has a challenge
that asks you to confirm that you want to clear the data.

Press [Y/+]. The display shows:
Are you sure?
2.
Press [Y/+] to clear the datalog or [MODE] if you do not want to clear the
datalog. If you choose to clear it, the display shows:

If you press [MODE], the display shows:

Important!
If you clear the datalog’s data, it cannot be retrieved, or “unerased.”
Change Datalog Period.
The datalogging interval can be set from 1 second to 3,600

64,000
datapoints.
