The last two calibration results are saved in the meter. Therefore, for 1-point calibration,
perform a 1-point calibration twice using the same standard solution, or initialize
calibration parameters (refer to Section 5.3 (11), “Initialize calibration parameters (I.CP)
panel”) before performing a 1-point calibration.
