11 Performing the measurement
The testo 883 can be operated both by joystick and by touchscreen on
the monitor.
ATTENTION
High thermal radiation (e.g. due to sun, fire, furnaces)
Detector may be damaged!
- Do not point the camera at objects with temperatures > 650 °C.
Ideal framework conditions
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 camera requires an adjustment time of
15 minutes after it is switched on.
Important camera settings
• Emissivity and reflected temperature must be set correctly in order to
precisely determine the temperature. Subsequent adjustment is possible via
the PC software, if required.
• When auto-scaling is activated, the colour scale is continuously adjusted to
the min./max. values of the current measurement image. This means that
the colour assigned to a specific temperature is changing constantly! To be
able to compare multiple images based on the assigned colour, scaling must
be set manually to fixed values, or must be subsequently adjusted to uniform
values using the PC software.
