Short summary
This paper covers procedures and requirements of two calibration methods and examines the necessary duration of acquisition of test measurements. Site-specific seasonal changes of environmental conditions cause small but noticeable fluctuation of calibration results. Calibration results within certain periods show a higher likelihood of deviation. These effects can partially be attenuated by including more measurements from outside these periods.
