Page 13: Degree Of Emission
6.3 Degree of emission Materials have different degrees of emission, i.e. they produce different quanti- ties of electromagnetic radiation. The degree of emission of the testo 845 is set at 0.95 ex-works. This is optimal for measurements of non-metals, plastics and food (paper, ceramics, plaster, wood, paints and lacquers). -

Measurement optics (Ratio distance : measuring point) Close f f ocus m m easurement Set close focus measurement in the instrument. - Page 19 8. Measuring Carrying o o ut m m easurements: Scrolling through the measurement menus is possible with the measure- ment trigger pressed down as well as in the Hold mode. Hold m m ode In the hold mode the last recorded measurement readings are frozen . Continuous m m easurement s s witched o o ff The instrument measures as long as the measurement trigger is pressed.
- Page 20 The surface moisture is measured from 0 to 1.0 (0 = dry, 1 = very damp). According to DIN EN ISO 13788, the danger of mould on surfaces exists if the moisture level rises above 0.8 over several days. The testo 845 calculates the surface moisture from the surface temperature (IR) and the dewpoint of the air.
