Maintenance and Troubleshooting
14.3 Storage, handling and transportation
Protect the instrument against the elements: rain, splashing, direct sunlight, etc.
A properly packaged instrument can be stored and transported at a temperature -20°C to +70°C
and relative humidity up to 80%. Best practice for packing the instrument for transportation is to
reuse the original packaging in which the instrument was first delivered. The instrument should
be stored in suitable premises, free of dust, condensation and chemical evaporation.
In cold weather, avoid sudden temperature change (like when entering a warm room) and give
the instrument enough time to adapt to the ambient temperature in order to avoid condensation
inside.
To clean the instrument, wipe the housing clean with a cotton cloth or tissue. Always clean the
instrument before storage. Pay attention not to scratch the surface of the display to retain good
clarity over time.
