标题: 非接触式温度计操作程序
SCOPE AND LIMITATIONS使用范围和限制
This procedure is limited to the operation of the non-contact thermometer manufactured by Raytek.
本操作程序仅限于Raytek 公司所生产的非接触测温仪器。
PROCEDURE操作程序
1)
How to operate the Unit
Pull open the unit’s handle using the finger indents near the trigger to access the C/F switch or to insert/remove the battery. To toggle between °C and °F, push the switch(A). Insert the 9v battery positive side first into the battery compartment. NOTE: The battery door is detachable.
握住扳机附近的手指槽，拉开手柄，按C/F的转换开关（A），可转换摄氏和华氏，放入9v电池，放入时正极先进，注意：电池盖可卸下。
To measure a temperature, point unit at object and pull the trigger. Be sure to consider distance-to-spot size ratio and field of view. If the unit is equipped with a laser, use the laser only for aiming. See How to Accurately Measure Temperatures.
要测量温度，请将测温仪对准物体并扣动扳机。务必考虑距离与测量点的比例和视场。如果测温仪装有激光，则激光仅用于瞄准。请参阅“如何精确测量温度”。
The backlit LCD displays the current temperature in Celsius or Fahrenheit. The unit will hold the reading for 7 seconds after trigger is released; the word HOLD appears. The presence of the battery icon indicates a low battery(B).
带背景光的LCD显示当前的摄氏或华氏温度，在释放扳机后，英文字母HOLD出现，且测温仪将保留读数7秒钟。如果出现电池图标，则表示电池电压低（B）。
2)
How to Accurately Measure Temperature
To find a hot aim the thermometer outside the area of interest, then scan across with an up and down motion until you locate the hot spot.
要找出热点，可将测温仪对准待测区域之外，然后上下扫描整个区域，直至找出热点。

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。
