9. MAINTENANCE
In order to ensure the accuracy of the thermometer for a longer period of time you should calibrate
it once a year.
Clean the device and the window of the display with a clean, lint-free, antistatic and dry cleaning
cloth.
Do no use cleaning agents that contain carbon or benzenes, alcohol or anything
similar to clean the product since these substances damage the surface of the
measuring instrument. Moreover, these fumes are hazardous to health and explosive.
Do not use tools with sharp edges, screwdrivers, metal brushes or anything similar to
clean the device.
