• Place pads under the reflector’s base as a last resort in high-vibration,
low-accuracy measurements.
You can also help factor out the vibrational effects by averaging successive
runs or averages.
Air turbulence is caused by temperature differences in the air. To
minimize the effect of air turbulence, follow these steps:
1. Remove sources of temperature fluctuations, such as open doors,
motors, lamps, exhaust fans.
2. Stir the air along the measurement path with a large fan to stabilize
the temperature.
