Working with the tube adapter
The tube adapter allows measurements on pipes and rounded objects. It can be measured on tubes with diameters from 4 mm on. The prism in the tube adapter ensures the required distance from the surface of the object on which measurement is to take place. Whether the tube adapter is positioned correctly, shows the tube to be measured: It is in parallel to the handle of the oil sensor, then.
For very small objects (short and small diameters), it may be advisable, to turn the sensor upside down and insert the object into the prism for measuring.
