The running measurement program is stopped when the
battery is changed. The stored data are preserved,
however.
1. Read out stored data, see testo ComSoft software instruction
manual.
If it is no longer possible to read out the stored data because
the battery capacity is too low:
> Change batteries and then read out the stored data.
2. Place the data logger on its front.
3. Open battery cover on the rear of the data logger by turning to
the left. Use a coin for this.
4. Remove empty batteries from the battery compartment.
5. Insert two new batteries (3 V button cells, CR 2032 lithium) into
the instrument so that the + pole is always visible.
