2) Field of View Make sure that the target is larger than the unit’s spot size. The smaller the target, the closer you should be to it. When accuracy is critical, make sure the target is at least twice as large as the spot size. 确保目标要比测点大,目标越小,您就应当越靠近它。当精确度很重要时,确保目标不小于测点的两倍。 As the distance(D) from the object increases, the spot size(S) of the area measured by the unit becomes larger. 随着测温仪(D)与物体间距离的增加,光点(S)增大。 Not recommended for use in measuring shiny or polished metal surfaces(stainless steel, aluminum, etc.). See Emissivity. The unit cannot measure through transparent surfaces such as glass. It will measure the surface temperature of the glass instead. Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit’s optics. ①建议不用于光亮或抛光金属表面(不锈钢、铝等)的测量,请参阅“发射率”。 ②测温仪不能透过玻璃类透明表面进行测定,它测定的将是玻璃的表面温度。 Most organic materials and painted or oxidized surfaces have an emissivity of 0.95(pre-set in the unit). Inaccurate readings will result from measuring shiny or polished metal surfaces. To compensate cover the surface to be measured with masking tape or flat black paint. Allow time for the tape to reach the same temperature as the material underneath it. Measure the temperature of the tape or painted surface. 大多数有机材料和涂有油漆或氧化的表面具有0.95的发射率(在测温仪中预先设定)。测量光亮或抛光的金属表面将导致读数不准确。解决方法是用黑胶带或黑色油漆盖住测定表面,让胶带有足够时间达到与其覆盖材料相同的温度,然后测定胶带或油漆的表面温度。 Lens Cleaning: Blow off loose particles using clean compressed air. Gently brush remaining debris away with a camel’s hair brush. Carefully wipe the surface with a moist cotton swab. The swab may be moistened with water. NOTE: DO NOT use solvents to clean the plastic lens. Case Cleaning: Use soap and water on a damp sponge or soft cloth. NOTE: DO NOT submerge the unit in water. 镜头清洗:用清洁压缩空气吹掉松散颗粒,轻轻用驼毛刷子刷去残留碎屑,再用潮湿棉花球小心擦洗表面。棉花球可用水湿润。注意:不要用溶剂清洗塑料镜头。 外壳清洗:用蘸有肥皂水的海绵或软布。注意:不要将测温仪浸在水中。 ---(on display)
