Maintenance and cleaning

The measuring device is absolutely maintenance-free, apart from
occasional cleaning. To clean the display, use a clean, lint-free, anti-
static and slightly damp cleaning cloth.

When the unit is moved from a warm location to a cold location (or vice versa),
this relocation can lead to condensation formation on the electronic measuring
equipment. This physical effect, which cannot be prevented for constructional
reasons, invariably leads to deviations in measurement. The unit requires an
"acclimatisation time" of approx. 15-30 minutes, depending on how high the
temperature differences were, before the measuring process can be continued.
