Introduction
Congratulations on your purchase of the Temperature Datalogger. This datalogger measures and stores up to
32,000 temperature readings. The user can easily set up the logging rate, high/low alarm and start-mode, and
download the stored data by plugging the module into a PC's USB port and running the supplied PC software.
Temperature data can then be graphed, printed, and exported to other applications. The data logger is supplied
with a long-life lithium battery, which can typically allow logging for one year. This meter is shipped fully tested
and calibrated and, with proper use, will provide years of reliable service

Battery Replacement
It is highly recommended that the battery be replaced every 12 months, or prior to logging critical data.
The TH10 does not lose its stored readings when the battery weakens or when the battery is replaced; the data
logging process will however be stopped and cannot be re-started until the battery has been replaced and the
logged data has been downloaded to PC.
Use only 3.6V lithium batteries. Before replacing the battery, remove the datalogger from the PC. Follow
diagrammatic steps 1 through 4 below.
NOTE: Leaving the RHT10 plugged into the PC USB port longer than necessary will cause some of the battery
capacity to be lost.
You, as the end user, are legally bound (Battery ordinance) to return all used batteries and
accumulators; disposal in the household garbage is prohibited!
You can hand over your used batteries / accumulators at collection points in your community or
wherever batteries / accumulators are sold!
Disposal: Follow the valid legal stipulations in respect of the disposal of the device at the end of its
lifecycle
