Environmental Considerations

MVR systems are factory calibrated under the standard laboratory environmental conditions
shown below:

Specification

Requirement

Ambient Temperature

20

°

C ± 0.5°C (68°F ± 1°F)

Humidity

40-60% RH

Temperature rate of change

0.5°C (1°F) per hour

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.
