Page 22: Optics
Measurement Optics The thermoMETER LS has switchable optics. The two possible operating modes are indicated as SF mode (Standard Focus) and CF mode (Close Focus). In the SF mode (standard operating mode) objects ≥ 16 mm can be measured. The measurement spot will be exactly marked with the patented crosshair laser, i.e. - Page 23 The measured area of the object (spot size) depends on the distance. For a correct measurement the spot size should have at least the same size like the object or should be smaller than that at all times. thermoMETER LS Page 23...

Page 60: Functional Principle
The specifications of the lens decisively determine the optical path of the infrared thermometer, which is char- acterized by the ratio Distance-to-Spot-size. The spectral filter selects the wavelength range, which is relevant for the temperature measurement. The detector in cooperation with the processing electronics transforms the emitted infrared radiation into electrical signals. thermoMETER LS Page 60... -
Page 61: Emissivity
Afterwards, determine the temperature of a directly adjacent area and modify the emissivity until the measured value corresponds to the temperature of the colored surface. On all three methods the object temperature must be different from the ambient temperature. thermoMETER LS Page 61... -
