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 mea-
suring spot of the IR thermometer. The measured temperature is the average temperature of the mea-
sured 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.
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.
Double targeting Laser
The double targeting lasers may be activated or deactivated. Press the measuring button (5) to switch on
the measuring device. Press the button for backlight and laser (8). When the laser is active, the "target-
ing laser active" indicator (15) is displayed. By pressing the button for backlight and laser (8) again, the
targeting laser is deactivated and the "targeting laser active" indicator (15) vanishes.
Backlight
Press the button for backlight and laser (8) to switch the backlight on or off while the measuring
device is switched on.
Setting the measuring unit (°C/°F)
Using the "up" (4) and "down" (7) buttons, you may select the the temperature unit "°C" (degrees Cel-
sius) or "°F" (degrees Fahrenheit) while the measuring device is switched on.
Data transmission USB interface (IR 1200-50D USB and IR 1600-50D USB)
The IR 1200-50D USB and IR 1600-50D USB have 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:
- Activate the USB interface in MIN, MAX, DIF or AVG mode by pressing the button for
backlight and laswer (8). Press the button until the "USB" symbol (25) appears on the
display.
- Start your computer with a Windows® 98SE or higher OS.
- Connect the lateral mini USB socket (3) of your measuring device to a free USB inter-
face on your computer with the enclosed USB cable.
