Introduction
Thank you for selecting the Extech Instruments Model TH10 Temperature Datalogger that measures
and stores up to 32,000 temperature readings. The user can easily set up the logging rate, high/low
alarm limits 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 device is shipped fully tested and calibrated and, with
proper use, will provide years of reliable service. Please visit our website (www.extech.com) to

TH10 LED Status Guide
* To save power, the TH10’s LED flashing cycle can be changed via the supplied software.
** To save power, alarm LEDs for temperature can be disabled via the supplied software.
*** LED status indication alternates every cycle. For example: If there is one alarm, the REC LED
blinks for one cycle and alarm LED will blink for next cycle.
**** When the battery is low, all operations will be disabled automatically. NOTE:
Logging automatically stops when the battery weakens (logged data will be
retained). The supplied software is required to restart logging and to download

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 or removed; 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 steps 1 through 4 below.
NOTE: Leaving the TH10 plugged into the PC USB port longer than necessary will reduce the
battery capacity.
Other Battery Safety Reminders
•Never dispose of batteries in a fire. Batteries may explode or leak.
Software Interface
The TH10 unit needs to be programmed using the supplied software before use.
The software can set the Sample rate, the temperature alarm limits, and the Start mode, as well as
download the recorded data from the logger.
Please refer to the Software Help guide that is supplied with the software to understand how to
operate the logger.
Check the software download page of the website www.extech.com for the latest version of the PC
