on two points

[alyonushka23]

Пожалуйста, помогите перевести предложение при калибровку прибора, точнее системы увлажнения зерна.
Я не могу понять, как перевести on two points:
The calibration is carried out on two points with the same type of wheat.

Контекст следующий:
By entering the values of the measured moisture, the system will calculate the equation of the right line interpolating the mean values. If the calibration is carried out according to the procedures, that is to say duly spacing the two points, with a use equal to the one used for the calibration, the system presents a reproducibility included between ± 0.3 %. The temperature changes of ± 15 ºC on the one of the calibration can be adjusted including the measure in the indicated tolerances.
Заранее спасибо
