6.3. 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 or optional
radio humidity probe slightly to shorten the adjustment time.
Avoid sources of interference (e.g. exhaled 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 maximum accuracy, the imager requires an adjustment
time of 10 minutes after it is switched on.
Important settings
Before recording an image, check whether the protection glass
option is set correctly to prevent corruption of the measurement
results, see Optics, page 57.
Before saving an image, make sure that it is correctly focussed,
manually (see Manually focusing the image, page 30) or
automatically (see Automatically focusing the image, page 30).
Images that are not in focus cannot be corrected retroactively!
To obtain precise measurement values, the emissivity and reflected
temperature must be set correctly, see Emissivity, page 42.
Subsequent adjustment is possible via the PC software, if required.
