How the Product Works
Infrared thermometers measure the surface temperature of an object. The Product
optics sense emitted, reflected, and transmitted energy, which is collected and
focused onto a detector. The Product electronics translate the signal into a
temperature measurement and shows the measurement on the display (see
Figure 3).

Product Operation
Temperature Measurement
To measure temperature, point the Product at an object and pull the trigger. You
can use the laser pointer to aim the Product. You can also insert the K-type
thermocouple probe for contact measurement. Be sure to consider distance-to-spot
size ratio and field of view (see “Distance and Spot Size” and “Field of View”). The
temperature is shown on the display.
Note
The laser is used for aiming purposes only and is not related to
temperature measurement.
The Product features an auto off function that automatically powers down the
Product after 20 seconds of inactivity. To turn the Product on, pull the trigger.
