VOLTCRAFT IR 1000-30D Bedienungsanleitung Seite 24

Measurement:
1. Point the measurement aperture (1) at the test object in as vertical a position as possible.
Make sure that the object to be measured is not smaller than the IR measurement spot
of the device (also see measuring spot size).
2. Press and hold down the measuring button (5). The measured value (24) is displayed.
The displayed value represents the average surface temperature of the IR measuring
spot. During the measurement, "SCAN" (13) is displayed.
3. When the measuring button (5) is released, the last measured value (24) is displayed for
about another 7 seconds so that it can be read more comfortably. "HOLD" (14) is dis-
played as well.
4. The device automatically shuts down 7 seconds after the measuring button (5) has been
released.
5. If the temperature measuring range is exceeded, "——" is displayed.
In order to determine the hottest spot of the test object, hold down the measuring button (5)
and scan the object to be measured in a zigzag movement until you have found the hottest
spot. The highest temperature measured will be displayed in the lower right corner as max-
imum temperature (22) if the max temperature function is activated.
For accurate measuring results, the infrared thermometer must have adapted to ambient
temperature. Always allow the device to reach ambient temperature when it is taken to a
new location.
Shiny surfaces lead to false results. For compensation, shiny surfaces can be covered with
adhesive tape or matte black paint. The device is not able to take measurements through
transparent surfaces such as glass. It measures the surface temperature of the glass.
Extended measurements of high temperatures at short distances will heat up the measuring
device and consequently result in faulty measurements. For accurate results, the following
rule of thumb applies: The higher the temperature, the higher the measuring distance and
the shorter the measurement duration should be.
