voltage may rise slightly after the unit turns itself off. In this event, the unit
may turn on momentarily as a result of a button press.
The batteries must be replaced before the recorded session(s) can be
downloaded from the instrument.
NOTE: Replacing the batteries while the unit is OFF will not result in the
loss of data memory. The internal backup capacitor will maintain the clock
and memory while the main batteries are being replaced. If the battery
level falls below the usable level or if the batteries have been removed
for an extended period of time, the clock time will be lost. However, the
recorded memory will be maintained since it is stored in Flash memory.
Event: Recording Session has Ended
The logger will be in STANDBY mode if one of the following occurs:
•
The session terminates due to recording end time being reached.
•
The recording in START/STOP mode fills the memory.
•
The user terminates the session by pressing the
until the STOP (ORANGE) LED lights up and releasing the button
before the next LED lights, or issues a Stop Recording command
from the Simple Logger
Under these conditions, it is possible to turn the logger ON from the
computer 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 until the START (GREEN) LED lights up and releasing the
button before the next LED lights, will start a New Session depending on
the available memory.
