HOBO Pendant Event/Temp Data Logger

Battery
The logger requires one 3

2032 lithium battery. Battery
life varies based on the temperature, the type of external switch,
and the frequency at which the logger is recording data (the
logging interval). A new battery typically lasts one year with
logging intervals greater than one minute. Deployments in
extremely cold or hot temperatures, or logging intervals faster
than one minute, may significantly reduce battery life. Continuous
logging at the fastest logging rate of one second will deplete the
battery in as little as two weeks.
To replace the battery:
1. Remove the two screws that secure the end cap to the case and
remove the cap. The circuit board is attached to the cap.
2. Examine the desiccant pack that is tucked below the battery
holder. If the desiccant is not bright blue, put the desiccant
pack in a warm, dry place until the blue color is restored.
3. Carefully push the battery out of the holder with a small,
nonmetallic blunt instrument.
4. Insert a new battery, positive side facing up.
5. Return the circuit board, desiccant pack, and label to the case,
carefully aligning the circuit board with the grooves in the
case so that the battery faces the ridged side of the case.
6. Replace the end cap, ensuring that the o
-
ring is seated in the
groove, and not pinched or twisted. Make sure no dirt or lint is
trapped on the o
-
ring, as this could result in a leak.
7. Re-fasten the screws. Do not over-tighten the screws.
WARNING:
Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium battery. The battery may
explode if the logger is exposed to extreme heat or conditions
that could damage or destroy the battery case. Do not dispose
of the logger or battery in fire. Do not expose the contents of
the battery to water. Dispose of the battery according to local
regulations for lithium batteries.
