Temperature alarm
Camera focus / Shutter-function
There is an option to set a temperature alarm for the three de Ö nable
measurement points (see chapter 10). An alarm tone will signalise
whether the measurement point is above, below or right within the
set temperature range.
In addition to the basic settings in the measuring tool, the camera
focus and the shutter function (image calibration) play an essential
role in achieving high-quality thermography results. You should focus
on the measured object as well as possible so that the outlines and
contours are clearly visible on the display. Measurements should
always be initiated by means of the "Shutter" button (image
calibration). This results in a brief mechanical shading of the sensor
in order to achieve the highest possible measuring accuracy. The
display will be frozen brie
× y during this operation.
To learn about activating the auto shutter function,
please see chapter 7.7.

Re ƃ ection temperature
Infrared measurements of speci Ö c objects can be affected by re × ection from other objects nearby or even
from the ambient air because the measured object cannot be fully isolated. The re × ection temperature
setting can help compensate for the interference. The re × ection temperature is generally the same as the
ambient temperature. However, if larger objects with signi Ö cantly different temperatures (approx. > 20 °C)
are in close proximity to the measured area, its effects must be taken into account. For this purpose, follow
these steps:
1. Set emissivity coef Ö cient to 1.0
2. Blur the object out of focus
3. Aim the camera in the opposite direction of the actual measured object
4. Determine the average temperature
5. Set the average temperature as the re
× ection temperature
Also follow the information in chapter 9.0.
