Look back at the measuring and gauging tools in task 05 and complete this text. 1. A  feeler gauge  controls the distance between two components. 2. A  straightedge  is proof of the evenness of areas with the light-gap method. 3. A  limit gap gauge  is proof of the diameter of shafts. 4. A  vernier calliper  is a tool to measure inside and outside dimensions. The dimension is determined by a measured value. The reading accuracy of the  vernier calliper depends on the vernier scale. There are also digital ones, which have an even higher accuracy. 5. An  external micrometer  is used, if the measuring accuracy of a vernier calliper is not enough 6. A  radius gauge  is a tool to prove the radius of an object. 7. A  dial gauge  is an instrument used to accurately measure small distances and amplify them to make them more obvious.  Dial gauges  with a scale interval of 0.01mm usually have a measuring range of 1mm, 5mm and 10mm. Precision  dial gauges  measure more precisely. 8. A  protractor  has a reading accuracy of 1°.
