561 Infrared Thermometer Introduction The Fluke 561 Infrared Thermometer (hereafter, the Thermometer) can determine the surface temperature by measuring the amount of infrared energy radiated by the target’s surface or by contact using a thermocouple probe. The Thermometer was designed specifically for use in heating, ventilating, and air conditioning (HVAC) applications. This manual covers all versions of the the Fluke 561. Note that the Japanese models indicate Celsius only. Contactin

561 Users Manual Safety Information XWWarning A Warning identifies conditions and actions that pose hazards to the user. To avoid electrical shock or personal injury, follow these guidelines: • * Do not point laser directly at eye or indirectly off reflective surfaces. • Before using the Thermometer inspect the case. Do not use the Thermometer if it appears damaged. Look for cracks or missing plastic. • Replace the batteries as soon as the battery indicator ( B) appears. • Do not use

561 Users Manual How the Thermometer Works Infrared thermometers measure the surface temperature of an opaque object. The Thermometer’s optics sense infrared energy, which is collected and focused onto a detector. The Thermometer’s electronics then translate the information into a displayed temperature reading which appears on the display. The laser is used for aiming purposes only. Operating the Thermometer The Thermometer turns on when you press the trigger. The Thermometer turns off
