5. Secure the battery-compartment door with its screw.
To remove the battery housing from the logger (in order to replace with a
new one or to change the battery type in use), see p. 23.
Lithium Batteries
For high-temperature applications, if the correct battery housing is fitted (see
p. 17), the logger can use four lithium thionyl chloride non-rechargeable AA
3.6 V cells. These are suitable for applications where the logger’s operating
temperature (i.e. the temperature of the logger itself) does not exceed
110°C/230°F.
WARNING
Only lithium batteries supplied by Datapaq, BP0021, are suitable for use with the
TP3 logger.
Life of Lithium Batteries
The data below can serve as a guide – though the values given are no more than
an indication of the battery life that can be expected. See p. 19 for general
considerations that affect actual battery life.
