Powering
the
Meter
All data loggers come with an international power adapter and are battery‐powered. Some meters
are powered by an internal rechargeable Li‐Ion battery and others by dry cell non‐rechargeable
alkaline AA batteries (not included), depending on the model of the meter. The table below shows
detailed information about the battery used by each available model.

Once the memory is full, the meter will continue to log new data over the original data beginning at
the first data point. Therefore, after each logging session you should use Gaslab
®
to save your data.
Because the data is stored in non‐volatile memory, data will be logged until the batteries are
exhausted. However, the logs files may not appear in Gaslab
®
. You can still extract them using the
“recover logs” feature in Gaslab
®
.
