If the button is not pressed within five seconds of arming, the erase oper-

1. Connect the instrument to the computer, then open the
Simple Logger
II Control Panel
.
2. Select
Erase Memory
from the
Instrument
Menu.
3. A dialog box will appear asking to confirm the erasure of the instru
-
ment’s memory. Select
Yes
to confirm or
No
to cancel the operation.
Erasing the memory will also clear any stored alarms.
