Infrared Thermometer Typical Measurements 11 • The most likely conditions for condensation form ation are low dry bulb te mperat ure and high wet bulb temperature (low temperat ure, high relat ive humidity). • Use the Fluke 971 to measure the attic/crawlspace relative humidity and determine the dew point temperature.
561 HVACPro Users Manual 12 Testing Contactors (Starters) 1. Press D to select emissivity. Press A to select LO for bright c ontacts, or MED for darkened contacts. 2. Press C and the press A to select MAX. 3. Measure line and load side of one pole without releasing trigger.
Infrared Thermometer Typical Measurements 13 Testing Bearings W Warning To avoid injury when t esting bearings: • Do not wear loose clothi ng, jewelry, or anything around neck when working around moving parts such as motors, belts, blower, and f ans.
561 HVACPro Users Manual 14 wall you should find parallel isotherm al rows indicating the location of heat t ubes below the surface. Perpendicular to the outside wall, you should fi nd rising and falling temp erat ures at equal distances.
Infrared Thermometer Typical Measurements 15 • If system pressure has been incr eased above design settings, this can result in sympto m of trap failure (stuck open). Check steam pressure. 1. Press D and then press A to select HI emissivity for bl ack iron pipe and painted traps.
561 HVACPro Users Manual 16 • All condenser return bend/hairpi ns should be at or slightly less than condenser saturation temperature. • If a group of return bends/hairpins do not confor m to expected temperatures, that indicates a blocked or restricted distri butor or dist ributor tube.
Infrared Thermometer Maintenance 17 Maintenance Changing the Battery To install or change the two AA batteries, open the battery compartment and insert the batteries as shown in Figure 2. Cleaning the Lens Blow off loose particles using clean compressed air.
