DFR0300Calibration: must I do two points or is one point enough?

Hi, during the calibration, is it necessary to complete two points calibration? Can I complete only one point calibration?
2024-07-11 20:28:33 The two points calibration must be completed because the two points respectively correspond to standard buffer solution 1413us/cm and 12.88ms/cm. The two points calibration ensure the accuracy of the entire measurement range. Therefore, two points calibration must be completed.
