6.2. Measuring
Important framework conditions
Please observe the following framework conditions in order to
obtain significant measurement results.
Humidity measurement:
• Pivot the separate humidity measuring instrument slightly to
shorten the adjustment time Avoid sources of interference (e.g.
breathed air).
Building thermography, investigating the building shell:
• Considerable temperature difference between inside and
outside required (ideal: > 15 °C/> 27 °F).
• Consistent weather conditions, no intensive sunlight, no
precipitation, no strong wind.
To ensure the highest level of accuracy, the imager requires an
equalization period of 5 minutes after being switched on.
Important settings
Before recording an image, check whether the protection glass
option is set correctly to prevent corruption of the measurement
results, Optics..., page 30.
Before saving an image, ensure that it is focused correctly (in
focus), see Focussing with the motor focus, page 18 or Manually
focusing the image, page 18. Images that are not in focus cannot
be corrected retroactively!
