measurement program. However, stored
measurement data are preserved.
1. Read out stored measurement data, see Reading out
measurement data.
✓ If it is no longer possible to read out the saved
measurement data because the battery capacity is too
low:
> Change the batteries and read out the stored
measurement data after.
2. Place the data logger on its front.
3. Loosen the screws on the back of the data logger.
4. Remove the battery compartment cover.
5. Take the empty batteries out of the battery
compartment.

temperatures below -10 °C you should use
