14. Logging data
The data logger is only dust-tight and water-jet proof when the USB protective cap (12) and the
rubber seals (9, 10) are attached. This protection allows permanent logging in damp rooms and
outdoors.
Before use, make sure that the USB protective cap is rmly attached to the data logger and the
casing is completely closed.
Do not immerse it in water!
Avoid operation near strong magnetic elds.
