4，測量技巧
如果物體的表麵覆蓋著霜凍，灰塵或其他材料。
請清潔表麵，以得到準確的測量結果。如果要被測量的物體的表麵
是高反射的具有非常低的輻射率值。請申請膠帶或申請啞光黑漆
到表麵，以提高精度。

4. Measurement Tips
If surface of object is covered with frost, dust or other materials.
Please clean surface to get accurate measure result. If the surface of an object to be measured
is highly reflective with very low emissivity value. Please apply masking tape or apply flat black paint
to the surface to improve the accuracy.
