10.4 Conducting a measurement
10.4.1 Preparing a measurement
Cleaning the measured object and the measuring machine
Contamination, e.g. from chips, dust and oil residues, leads to incorrect
measurement results. The measured object, the holder for the measured object,
and the sensor must be clean before you start measuring.
Clean the measured object, the holder for the measured object, and the
sensors with appropriate cleaning products
Stabilizing the temperature of the measured object
The objects to be measured should be stored at the measuring machine for
an appropriate amount of time to allow the objects to adjust to the ambient
temperature. Since the dimensions of the measured objects vary with temperature
changes, the temperature of the measured objects must be stabilized.
This ensures the reproducibility of the measurement. The reference temperature is
usually 20 °C.
Stabilize the temperature of the measured objects for an appropriate amount
time
Reducing environmental influences
Environmental influences, such as incident light, ground vibration or air humidity,
can affect the measuring machine, the sensors or the measured objects, and thus
falsify the measurement results. Certain influences, such as incident light, also
have a negative effect on the measurement uncertainty.
Eliminate or avoid environmental influences as far as possible
