Most common reasons for measuring errors: infrared temperature
•
Wrong emission ratio: see chart on page 23 or other appropriate source
•
Polluted sensor: clean the sensor with light compressed air
•
Incorrect distance to the measuring object and therefore too large
measuring spot
•
A measurement at glass can lead to reflexion, and according to the
incident angle the illuminated object is measured.
Most common reasons for measuring errors: air humidity
•
Sunlight or other sources of heat or cold which do not correspond to the
surrounding temperature
•
Measuring errors due to too short conditioning -> see page 24
•
Dripping or sprayed water
•
Irreversible damage of the sensor due to aggressive gases
•
Danger of condensation because of changing temperature
•
Polluted moisture sensor
•
Foreign objects on the sensor: remove with light and dry compressed
air.
Most common reasons for measuring errors: CO

•
Breathing air at the sensor strongly influences the measuring result.
•
For long-time measurements regularly check the battery condition.
