561 Users Manual Table 3 lists recommended Fluke temperature probes for use with the Thermometer: Probe 80PK-25 80PK-1 80PK-8 80PK-26 80PK-9 80PK-11 Table 3. Recommended Temperature Probes Usage The piercing probe is the most versatile option. Good for checking air temperature in ducts, surface temperature under carpets/pads, liquids, thermometer wells, vent temperatures, and for penetrating pipe insulation. The general purpose bead probe is an alternative, for quick, accurate surface temperatures and air temperatures within ducts, vent temperatures. Pipe clamp probes (2) are essential for tracking continuously changing temperature differentials on hydronic tubing and pipe loops, and good for quick, accurate refrigerant temperatures. The tapered probe is a good general-purpose gas and surface probe, with a good length and low mass tip casing for faster reaction to surface and air temperatures. The insulation piercing probe provides a sharp tip to pierce pipe insulation and flat probe tip for good surface thermal contact, air temperatures within ducts, and vent temperatures. The Velcro pipe probe is a convenient way to attach a thermocouple to a pipe while keeping hands free. HOLD The display will remain activated for 7 seconds after the trigger is released. HOLD appears in the upper middle of the display. When the trigger is pulled again, the Thermometer will begin measuring in the last function selected. 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. Carefully wipe the surface with a moist cotton swab. The swab may be moistened with water. Cleaning the Housing Use soap and water on a damp sponge or soft cloth. WCaution To avoid damaging the Thermometer, do NOT submerge it in water. 10
