Operating Instructions Taking Measurements To take a temperature measurement using your INF155, you simply point the aperture at an object and pull the trigger. The object’s temperature will show up on the display and update at a rate of approximately 2 times per second. There will be a delay of approximately one-second between the time you initially pull the trigger and the time the display comes on. The 60second auto-hold initiates at the moment you release the trigger.
Battery Indicators The thermometer incorporates visual low battery indications. Lens Care The sensor lens is the most delicate part of the thermometer. The lens should be kept clean at all times. Care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol. Allowing the lens to fully dry before using the thermometer. Do not submerge any part of the thermometer in liquids.
The other common question is regarding emissivity. In simple terms e m i s s i v i tyis a percentage of energy emitted from a surface compared to the energy emitted from a black body source. If a surface emits one half (1/2 or 0.5) the amount of energy at a given temperature and wavelengt h as a black body, it is said to have an emissivity of 0.5. Surfaces closest to the balck body level would be flat black, and those farthest from it would be mirror or chrome surfaces.
