the logger to the outside of the unit. Allow at least 1 hour for the sensor to reach
equilibrium before activating the logger. When the sensor doesn’t have enough
time to equilibrate to the internal temperature, it will trigger a false alarm if it is still
above the high alarm set point.
Starting the Logger
Press and hold the
START
button until a temperature reading appears on the
LCD without flashing. If the glycol bottle is inside the storage unit and was
allowed to acclimate for at least 1 hour, it will be simulating the temperature of
the vaccines vials stored around it. If
LLL.L
appears on the
LCD, the sensor is not connected. Check the stereo jack to
make sure it is completely inserted.
Daily Statistics on LCD
Temperature statistics from the last 24 hours of recorded data are available for
viewing on-demand at any time without stopping the logger.
A single press of the green
START
button shows a statistic on the LCD, each
subsequent button-press advances to the next statistic. The LCD automatically
reverts to current reading about five seconds after button release and showing a
statistic. The LCD scrolls through values in this order:
•
Maximum temperature
•
Minimum temperature
•
Average temperature
If alarms limits are programmed:
•
High alarm set point
•
Accumulated time above high alarm, if no excursions, 00:00 is displayed
•
Low alarm set point
•
Accumulated time below low alarm, if no excursions, 00:00 is displayed
Inserting Waypoints
If a temperature reading needs to be confirmed at a check point during
transportation or storage, a waypoint can be inserted as a marker to flag date/
time of this event. The waypoint option must first be enabled during logger
configuration.
Press and hold the
START
button until
FLA9
appears on the
LCD and release when it stops flashing. The waypoint has
been inserted and the LCD will revert to current temperature
reading. When reports are created at the end of the logging
period, waypoints appear as a vertical line on the graph and have an asterisk in
the data table.
