Measurement Stability
Take into account that instruments require sufficient time to adjust to the ambient
temperature. The following rule-of-thumb for a high precision measurement applies:
Temperature difference in degree Celsius (°C) x 2 = duration in minutes required for
the instrument to adjust to the new temperature.
Avoid sighting across fields with intense heat shimmer by sun light, e.g. at noon.
