INTRODUCTION

Thank you for purchasing General Tools & Instruments’ (General’s) IRT217 Infrared Thermometer (IRT). The instrument uses an IR sensor to measure the temperature of a surface or object from a distance by quantifying its thermal radiation. This non contact measurement capability allows you to safely determine the temperature of very hot or cold surfaces, hard-to-reach or moving objects, and toxic substances. A red laser with a targeting ring precisely outlines the area being measured. Readings, in °F or °C, are displayed on a liquid-crystal display (LCD).

The IRT217 has:

• A 10:1 distance-to-spot (D:S) ratio
• A high-visibility, 4-digit white-on-black backlit LCD
• A measurement range of -4° to 689°F (-20° to 365°C)
• Automatic reading hold
• A 7-second Auto Power Off (APO) function

WHAT’S IN THE PACKAGE

The IRT217 comes on a blister-packed card along with two “AAA” Alkaline batteries.

SAFETY INSTRUCTIONS

WARNING!

• Do Not Use For Human Body Temperature

CAUTION!

• The IRT217’s Class 3R laser pointer emits less than 3mW of radiation at 630 to 660nm (nanometers). However, avoid looking directly at the laser, and never point it at people or animals. Eye protection is normally afforded by the blink refl ex.
•  Never allow children to operate the instrument.
• Do not operate the IRT217 in explosive environments containing flammable liquids, gases or dust. Doing so may create sparks that can ignite the dust or fumes.
• Keep the IRT away from cardiac pacemakers. A magnet inside the instrument generates an electromagnetic field that can impair their function. Likewise keep the tool away from magnetic data storage media, whose contents may be erased by the magnetic field.

SETUP INSTRUCTIONS

INSTALL BATTERIES
The IRT217 is ready to use after you install two “AAA” batteries.
To open the battery compartment (Fig. 1, Callout D), place the tips  of your thumb and index finger in the cutouts on the sides of the  compartment cover and pull to swing it down. Install the batteries in series according to the polarity marks on the inside of the compartment. Then swing the cover up and snap it shut.

OPERATING INSTRUCTIONS

To make a temperature measurement, begin by squeezing the IRT’s trigger (Fig. 1, Callout C) to activate its laser pointer. The display will come to life by showing a temperature reading, as well as the flashing word SCAN (Fig. 2, Callout F). Note that the reading changes as you change the target with the trigger squeezed.
Next, while continuing to squeeze the trigger, choose your target  area—the area whose temperature you wish to measure—and aim the gun at it. Move closer to or further from the target so the visible targeting ring produced by the IRT exactly covers the target area. Be sure the ring does not extend beyond the target area—in which case the measurement might include hotter or colder surfaces outside its perimeter, producing an erroneous reading.

Once you’ve defined the target area, release the trigger. Doing so changes SCAN to HOLD (Fig. 2, Callout G) and “freezes” the readout at the temperature of the target for seven seconds.
After seven seconds, the IRT217 (including the laser pointer) automatically powers off to extend battery life. The seven-second hold enables you to take the temperature of surfaces you cannot see (under or behind objects, for example) and then read the display after returning the gun to eye level.
To change the measurement unit from Celsius to Fahrenheit, press the ºC/ºF button (Fig. 1, Callout G.). To turn off the laser pointer, press the button (Fig. 1, Callout F).

OPERATING/MAINTENANCE TIPS

• The display indicates OH if the temperature of a target is above 689°F (365°C), and OL— if its temperature is below -4°F (-20°C).
• While making measurements, the brightness of the laser and the display back light will gradually decrease along with battery charge. This will not affect the accuracy of measurements.
• When the batteries become critically short of power, the icon will automatically appear on the screen. When it does, replace both batteries.
• The IRT217 may not be able to measure the temperature of computer/TV monitors because they absorb IR radiation. Similarly, attempting to measure the temperature of a target behind glass, plastic or steam may produce erroneous results.
• To avoid having old or unused batteries leak acid and ruin the instrument, remove both batteries when you do not expect to use the IRT217 for a long period of time (several months, for example).
• Clean the lens of the infrared sensor lens (Fig. 1, Callout B) often with compressed air or a moist cotton cloth. Never use a solvent or an abrasive cleaner. To clean the housing, use a soft, damp cloth.
• Abrupt temperature changes will cause condensation and possible vapor penetration. Clean the LCD after the vapor evaporates.
• Keep the IRT217 away from water, extreme temperatures, corrosive gases and strong electromagnetic fields (such as produced by arc welders and induction heaters).
