Battery Replacement
It is highly recommended that the battery be replaced every 12 months, or prior to
logging critical data.
The RHT10 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.
WARNING: Handle lithium batteries carefully, observe warnings on battery casing. Dispose of in
accordance with local regulations.
Safety: Please dispose of batteries responsibly; never dispose of batteries in a fire, batteries may
explode or leak. If the meter is not to be used for 60 days or more, remove the battery and store
separately.
