Basic Maintenance
Basic maintenance required by the thermometer is discussed in this section.
Cleaning the Thermometer
Caution
•
To avoid damaging the thermometer, do not use aromatic hydrocarbons or
chlorinated solvents for cleaning. These solutions react with the plastics
used in the thermometer.
•
Do not allow the LCD to get wet.
•
Do not remove any of the lubricant from the input terminals.
