Cleaning
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.
The unit’s back cover is fitted with rubber rings. After replacing the battery,
check that the rubber rings are properly seated before reinstalling the back
cover. Improper seating of the rubber rings will compromise the unit’s water-
resistant structure, and possibly result in damage to the equipment.
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.
