Field of View The meter’s field of view is 8:1, meaning that if the meter is 8 inches from the target, the diameter of the measurement spot (target) is 1 inch. Other distances and spot sizes are shown below in the field of view diagram. Refer to the chart printed on the meter also for more information. Diameter of Spot 2” 1” 0.5” 4” Laser pointer 4” 8” 16” 32” Distance from Object IR Measurement Notes 1.

Maintenance Cleaning Wipe instrument with damp cloth as needed. Do not apply solvents or abrasives to the meter. Store in a cool dry place with the batteries removed. Battery Replacement When the batteries weaken, the LCD display will dim or go completely blank. To replace the batteries, open the rear battery compartment and insert four (4) new 1.5V ‘AA’ batteries with correct polarity position.
Emissivity Considerations The amount of IR energy emitted by an object is proportional to an object's temperature and its ability to emit energy. This ability is known as emissivity and is based upon the material of the object and its surface finish. Emissivity values range from 0.1 for a very reflective object to 1.00 for a flat black finish. The 42580 senses IR energy and calculates the temperature based upon the amount of IR energy it receives using a factory default emissivity setting of 0.
Software System Requirements • Hardware Requirements: 486 PC or better with COM 1 and COM 2 Serial ports • Operating System Compatibility: Windows TM 95/98/NT/2000/XP Hardware Connection The IR Thermometer connects to a PC with the supplied DB-9 to 3.5mm mini-plug (mono) interface cable.
