Non-Contact Infrared Thermometers
② Open battery cover, then take out the battery from
instrument and replace with a new 9-Volt battery and
place the battery cover back.

6. NOTES:

How it Works
Infrared thermometers measure the surface temperature of an
object. The unit's optics sense emitted, reflected, and
transmitted energy, which is collected and focused onto a
detector. The unit's electronics translate the information into a
temperature reading, which is display on the unit. In units with
a laser, the laser is used for aiming purposes only.
Field of View
Make sure that the target is larger than the unit's spot
size. The smaller the target, the closer you should be
to it. When accuracy is critical, make sure the target is
at least twice as large as the spot size.
Distance & Spot Size
As the distance (D) from the object increases, the spot
size (S) of the area measured by the unit becomes
larger. See: Fig: 1.
