Page 2: Wide Range Application
Features • Precise non-contact measurements • Built-in laser pointer • °C/°F switchable button • Automatic Data Hold & Auto power off • Measures a 1 inch target from a distance of 8 inches • Backlit LCD display Wide range application Food preparation, Safety and Fire inspectors, Plastic molding, Asphalt, Marine and screen printing, measures ink and dryer temperatures, Diesel and Fleet maintenance. Field of View Meter’s field of view is 12:1, meaning that if the meter is 12 inches from the target, the diameter of the object under test must be at least 1 inch. Other distances are shown below in the field of view diagram. Refer to the chart printed on the meter for more information. -

Safety • Use extreme caution when the laser beam is turned on. • Do not let the beam enter your eye, another person’s eye or the eye of an animal. • Be careful no to let the beam deflect off reflective surface which could strike your eye. • Do not allow the laser light beam impinge on any gas which can explode.

Note: Measurement considerations Holding the meter by its handle, point the IR Sensor toward the object whose temperature is to be measured. The meter automatically compen- sates for temperature deviations from ambient temperature. Keep in mind that it will take up to 30 minutes to adjust to wide ambient temperatures. Several minutes is required after a low temperature is measure before a high temperature measurement can be measured. This is a result of the cooling process which must take place for the IR sensor. - Page 7 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 displayed 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.
