RT-3, RT-5x, RT-7x and RT-9x Thermal Imagers

Measurements

High thermal radiation (e.g. due to sun,
NOTI E
fire, furnaces) may damage the Detector. To pre-
vent damage to the thermal imager, do not point
directly at the sun or other intense light sources.
Do not point at objects with temperatures outside
the measuring range of the tool, see specifica-
tions.
The accuracy of the thermal imager
NOTI E
temperature measurements depends on the spe-
cific settings of the tool. Emissivity and Reflected
Temperature settings can significantly affect ac-
curacy. If using the Automatic Scaling function,
the color assigned to a temperature is continu-
ously changing, and color should not be used to
compare temperatures. Use a fixed scale if color
will be used to compare temperature.
These conditions can significantly affect the ac-
curacy of measurements with thermal imagers:
• Emissivity and reflected temperature settings.
• When performing building thermography (in-
vestigating heat moving through the building
shell), a greater difference between inside
and outside temperature (ideal: ≥ 15°C/≥
27°F) improves accuracy.
• Weather conditions that can create large
changes in temperature (Such as intense
sunlight heating a surface, winds or rain that
can significantly cool a surface).
• The thermal imager requires a warm up and
equalization period of up to 10 minutes after
being turned on to maximize accuracy.
• Distance to surface. The surface must be rec-
ognizable and clear, and larger than the IFOV
warner cursor.
It is the operator's duty to evaluate these condi-
tions to assess the effect of the condition and
quality of the measurements.
