3.6 Environmental Considerations
MVR systems are factory calibrated under the standard laboratory environmental conditions
shown below:
20°C ± 0.5°C (68°F ± 1°F)
Temperature rate of change
If the system is to be operated under environmental conditions that are substantially different
from those shown above, the system should be recalibrated under the expected conditions
.
Users should also consider the
material characteristics of the parts under inspection, in particular
coefficients of thermal expansion. Numerical compensation may be required when measuring
parts under conditions different from those controlling the stated dimensional specifications for
these parts.
