IR measuring spot size - distance-to-spot ratio (D/S)
In order to obtain accurate measuring results, the object to be measured must be larger than the IR
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 to the infrared thermometer
must be. See the following diagram for the exact measuring spot size. The diagram is also printed
on the device. For exact results, the object to be measured should be at least twice the size of the
measuring spot.
Spot
Distance
The ideal measuring distance for these two infrared thermometers is at the focal point
of the two targeting lasers, because these offer the best measuring accuracy. The
measuring spot size at the focal point is 18 mm.
Double targeting Laser
The double targeting lasers may be activated or deactivated. Press the measuring button to switch
on the measuring device. Press the button for backlight and laser. When the laser is active, the
"laser symbol" is displayed. By pressing the button for backlight and laser again, the targeting laser is
deactivated and the "laser symbol" vanishes.

Backlight

Press the button for backlight and laser to switch the backlight on or off while the measuring
device is switched on.
Setting the measuring unit (°C/°F)
Using the "▲" and "▼" buttons, you may select the the temperature unit "°C" (degrees Celsius) or
"°F" (degrees Fahrenheit) while the measuring device is switched on.
Data transmission USB interface
The device has an integrated USB interface to transmit temperature data to and store the measured
values on a computer. Connect the infrared thermometer to your computer by the following steps:
1. Activate the USB interface in MAX, MIN, DIF or AVG mode by pressing the button for backlight and
laser. Press the button until the "USB" symbol appears on the display.
2. Start your computer with a Windows® 98SE or higher OS.
3. Connect the lateral mini USB socket of your measuring device to a free USB interface on your
computer with the enclosed USB cable.
