Event: Recording Session has Ended
The logger will be in STANDBY mode, if one of the following occurs:
• The Recording Session terminates due to recording end time
being reached when recording in the Start/Stop mode.
• The recording in Start/Stop mode fills the memory.
• The user terminates the Recording Session by pressing the
PRESS
button for >3s or issues a Stop Recording command
from the
Sentinel Control Panel
.
Under these conditions, it is possible to turn the logger ON from the com-
puter to download the data, if the batteries have sufficient power.
The logger is now ready for a New Session or Download. Pressing the
PRESS
button for more than 1.5 seconds but less than 3 seconds will start
a New Session depending on the available memory.
4.9 Reset Button Operation
There is a recessed
RESET
button located inside the unit and indicated
by a label on the shield.
It is recommended that the
RESET
button be pressed only when the logger
stops responding to the normal press button control when not connected
to the
Sentinel Control Panel
. It is not recommended to reset the instru-
ment when the logger is recording, downloading or being configured.
Pressing the
RESET
button when the logger is ON will cause the
instrument to reset its configuration to factory defaults.
NOTE:
In an effort to preserve recorded memory, the instrument will
set the memory available to zero when the RESET occurs. This means
that any prior session will remain in memory and may be available to
be downloaded until the memory is erased.
Event: Pressing the RESET Button while Recording
(not recommended)
• The RED LED remains OFF.
• The recording session ends and the GREEN LED changes from
a double-blink to a single-blink.
• The YELLOW LED double-blinks to indicate that the memory is full
