10 Maintenance and adjustment
When used in the area of climate-control technology, we
recommend annual maintenance.
Before it is checked or adjusted the device should be stored at
a temperature of approx. 20°C..25°C for 12 hours.
Recalibration should only be carried out by specialist staff or,
better still, at accredited laboratories.
Clean the device with a damp cloth as and when necessary. Do
not use any cleaning fluids, just plain water to dampen the
cloth.
