Reply to "Novice calibration course questions"

dalesummersMember

I have noticed that weather conditions affect the difference between the out and back calibration course measurements. When I and my two assistants measured a 500 meter calibration course in Detroit Lakes, MN last September, we had 500.000 meters each way. We measured back to the start mark within 2 mm. The temperature remained at 58 degrees F and it was cloudy. Whenever the temperature has changed during measurement, my out and back calibration course measurements have been different. I always have two people help me measure a calibration course.
