OPERATION
1) Pull and hold trigger (laser pointer is on as default setting) to turn on LCD display reading &
battery icon. Release the trigger and the reading will hold for approx. 15 secs.
2) Locating a hot spot: Aim the thermometer outside the area of interest. Scan across the area in
an up and down motion unit the hot spot is located while holding the activation trigger. The
thermometer will continue to read the surface temperature while the activation trigger is
depressed.
Note
Holding the trigger should last about 1 second at least.
3) Fahrenheit & Celsius Conversion: Press the ℉/℃ button to switch from Fahrenheit to Celsius
readings.
4) Press the Laser ON/OFF button to turn the laser pointer on or off.
5) The object being tested should be larger than the spot size calculated by the field of view
diagram printed in this manual or on the unit itself.
Field of View
The farther the thermometer is from the target, the larger the target area will be. This relationship
between distance and target size is normally expressed as the distance to spot, or D:S ratio, at a
distance of 8 feet, the “target” spot would be 1 foot in diameter. The thermometer will display the
average temperature across the target area.
Emissivity
Most organic materials and painted or oxidized surfaces have an emissivity of 0.95. This unit is
preset at 0.95. Inaccurate readings will result from measuring shiny or polished metal surfaces. To
compensate, cover the surface to be measured with masking tape or flat black paint. Measure the
tape or painted surface when the area has reached the same temperature as the material
underneath.
