Page 16: Locating A Hot Or Cold Spot
K-Type Thermocouple Measurement X� To avoid electrical shock or personal injury, do not connect the thermocouple contact probe to live electrical circuits. The thermometer comes with a bead K-type thermocouple probe. K type thermocouple is connected to the thermometer via TC-K input connector located on right side of the thermometer. -
Page 17: Field Of View
Field of View Make sure that the target is larger than the spot size. The smaller the target, the closer you should be to it. -
Page 18: Emissivity
Emissivity Emissivity describes the energy-emitting characteristics of materials. Most organic materials and painted or oxidized surfaces have an emissivity of about 0.95. If possible, to compensate for inaccurate readings that may result from measuring shiny metal surfaces, cover the surface to be measured with masking tape or flat black paint (<150°C / 302°F ) and use the high emissivity setting. - Page 19 2. The instrument cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead. 3. See table of Surface Emissivity for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.).
