• Press the ON/OFF button to turn the unit on.
Switching On and Off
• Press the ON/OFF button a second time to turn the unit off.
NOTE: The unit will automatically turn off after 10 minutes. External Operating
Temperature Range is -4
• For detecting small temperature changes of 1º F (0.5º C), press the +/- TEMP button to
Setting Threshold for Color Change:
set to the 1º setting on the LCD screen of the detector.
• For detecting medium temperature changes of 5º F (3º C), press the +/- TEMP button
to set to the 5º setting on the LCD screen of the detector.
• For detecting large temperature changes of more than 10º F (5.5º C), press the +/-
TEMP button to set to the 10º setting on the LCD screen of the detector.
• If you do not want the LED spot to change color, press the +/- TEMP button to set at "- - ".
You can change the threshold setting while you are scanning. If the color is changing
erratically, try increasing the "+/- TEMP" setting. If you see a temperature difference on
the screen, but the light is not changing color, try reducing the "+/- TEMP" setting.
Using the IR Thermometer
• Aim the unit near the location you want to scan for a draft or thermal leak. This initial
aim point will be your reference target.
• Squeeze the On/Off button.
• Keep the unit aimed at the reference target until the green light shines on the
target and a Reference Temperature appears on the screen.
• Slowly scan the IR Thermometer across the area of interest. If the scanned
temperature is hotter than the reference temperature by more than the threshold, the
light will turn from green to red. If the scanned temperature is colder than the reference
temperature by more than the threshold, the light will turn from green to blue.
• Scan around a light fixture to determine if ceiling insulation was removed during
Examples of Use:
installation.
• Scan along window and door sills to see where to add weather-stripping.
• Scan where a wall and the floor meet to find drafts that should be caulked.
• Scan an attic door to see if you need to add insulation.
NOTES*:
• Shiny or polished surfaces can give inaccurate readings. To compensate for this, cover
the surface with masking tape or flat colored paint. When the tape or paint reaches the
same temperature as the target underneath, measure the temperature of the item.
Emissivity describes the energy-emitting characteristics of materials. Materials with low
emissivity value such as shiny or polished surface can give inaccurate readings.
• The thermometer cannot measure through transparent surfaces such as glass or
plastic. It will measure the surface temperature instead.
• Steam, dust, smoke, and other optical obstructions can prevent accurate
measurement. Hold the thermometer back and at an angle for an accurate
measurement.
