Routine Maintenance
General Notes:
Boomerang 2 is a precision electronic instrument and precautions should be taken to
avoid moisture or excessively dirty/dusty conditions. Small plastic pouches/protective bags can be used.
Battery Life:
Approximately every 6 months, Boomerang 2 will require a new battery. Boomerang 2 will
display "BAT REP" on LCD. The instrument will not START until battery is replaced and the RESET box is
checked with Boomerang Setup in KoldLink software.
Battery Replacement Procedure:
Boomerang 2 requires a CR 2450 coin cell lithium battery (available
locally or from Cargo Data Corporation). Remove battery compartment door screws using a small (#2)
Phillips type screwdriver. Gently lift battery from its holder.
Once old battery has been removed,
WAIT 30 SECONDS
. This is necessary to allow residual electrical
power within Boomerang 2 to discharge.
After 30 seconds have elapsed with no battery in Boomerang 2,
install new battery. Before replacing battery door, ensure the moisture protective clear gasket fits into
the groove around the battery door area. Boomerang 2 will issue 5 beeps to confirm successful battery
installation. If you do not hear five beeps after battery installation, remove battery, wait 30 seconds,
then repeat procedure.
Sensors:
The Boomerang 2 temperature sensor is a small black device mounted to the sensor port in
the lower right corner of the instrument. In the event you wish to use extension sensors or probes (to
monitor internal temps of solids or liquids), gently slide the sensor out and replace with extension
sensor or probe (available separately from Cargo Data). When removing sensor or probe cables from
Boomerang 2, gently grasp the plug body, and apply pressure to remove from Boomerang 2 .DO NOT
PULL ON CABLES. Re-install the connector by gently inserting the connector, with the screw side down
and ridges showing. Push gently but firmly to completely seat connector into Boomerang 2.
Note:
If Boomerang 2 is activated with sensor removed, the temperature samples recorded
during the sensor’s absence will show 127 F.
Troubleshooting
If you receive an error message when attempting to download Boomerang into KoldLink software, check
port selection under "tools\options". Choose port option that includes “Silicon Lab UART “ in its
description. Other devices or drivers can interfere with the USB port, such as cameras, etc. that use the
same port. For additional troubleshooting information, consult the KoldLink download page on
