Accuracy is specified for ambient temperatures between +18 oC (+64 oF) and +28 oC (+82 oF) for a period of 1 year. The above specifications do not include thermocouple error.

Accuracy is unspecified when the input lead length is resonant with the interfering frequency.

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.
