In order to determine the hottest spot of the test object, hold down the measuring but-
ton (7) and scan the test object in a zigzag movement until you have found the hottest
spot. In the secondary display (20), the device displays minimum (MIN), maximum
(MAX), and average temperature (AVG) as well as the temperature difference (DIF).
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 result in false results. For compensation, shiny surfaces can be covered
with adhesive tape or matt black paint. The device is not able to take measurements
through transparent surfaces such as glass. It measures the surface temperature of the
glass.
Lengthy measurements of high temperatures at a short distance will heat up the mea-
suring 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.
IR measuring spot size - distance-to-spot ratio (D/S)
In order to obtain accurate measuring results, the test object must be larger than the measuring spot of
the IR thermometer. The measured temperature is the average temperature of the measured area. The
smaller the test object, the shorter the distance must be to the infrared thermometer. See the following
diagram for the exact measuring spot size. The diagram is also printed on the device. For exact results,
the test object should be at least twice the size of the measuring spot.
