Infrared thermometer
Important information on product safety!
• Do not expose the device to extreme temperatures, vibrations or
shocks.
• Protect the unit from large or abrupt ambient temperature
changes.
• Do not leave the unit near objects of high temperature.
• Do not immerse the unit in water. Water can penetrate and cause
malfunction. Protect it from moisture.
• Check the housing before using the device. Do not use the device
if it seems to be damaged. Check for cracks or missing plastic
parts.
• Steam, dust, smoke, etc., can prevent accurate measurement by
obstructing the unit’s optics.
EMC/RFI
• Protect the unit from EMI (Electro Magnetic Interference) from
induction heaters and microwave ovens and Electro Static Dis-
charge. Readings may be affected if the unit is operated within a
radio frequency electromagnetic field strength of approximately 3
volts per meter, but the performance of the instrument will not be
permanently affected.
3. Getting started
• Open the battery compartment.
• The battery compartment is on the inside of the handle. Open the
battery compartment cover downwards.
• Insert two new batteries 1,5 V AAA. Ensure that the batteries
polarity is correct.
• Close the battery compartment again. The cover is properly
inserted in the housing, as soon as a click is heard.
4. Use
• Press the measuring button on the inside of the handle to turn on
the device.
• The device will alert you with a beep.
• All segments will be displayed for a short moment.
• The backlight is automatically activated (default). The symbol
appears on the display.
• Press the
button to turn off or turn on the backlight. The sym-
bol disappears or appears on the display.
• The laser is automatically activated (default). The symbol
appears on the display.
• Press the
button to deactivate or activate the laser. The symbol
disappears or appears on the display.
• Press and hold the measuring button, on the display appear
"SCAN" and the measured temperature.
• With the laser the measuring point can be focused exactly.
• Release the measuring button.
• On the display appears HOLD.
• The latest measured temperature stays for a few seconds on the
display.
• When the device is not used, it will automatically switch off after a
few seconds.
• Press the °C/°F button to change the temperature display from °C
(default) to °F.
5. Distance, Spot Size, and Field of View
• As the distance (D) from the object increases, the spot size (S) of
the area measured by the unit becomes larger a ratio D:S = 12:1
(e.g. 120 cm distance = 10 cm spot size). To get the most accurate
temperature reading, aim at the target as near as possible.
• Should the distance be too great, there is a risk that the tempera-
ture has also been taken outside the aimed target.
Please take note of the following:
• Not recommended for use in measuring shiny or polished metal
surfaces (stainless steel, aluminium, etc.).
• The unit cannot measure through transparent surfaces such as
glass or plastic. It will measure the surface temperature of the
glass instead.
6. Care, maintenance, battery replacement
• The sensor lens is the most delicate part of the thermometer.
Please protect the sensor part from dirt.
• Clean your instrument with a soft damp cloth. Do not use sol-
vents or scouring agents.
• Remove the batteries if you do not use the product for a long
period of time.
• Change the batteries, when the battery symbol appears on the
display.
• Confirm the device is power off before changing the batteries.
