After the fifth buffer has been measured the calibration is automat-
ically finished. Then the calibration record is displayed.
The calibration line is determined by linear regression.

Calibration points

Calibration can be performed using one to five buffer solutions in any order
(single-point to five-point calibration). The meter determines the following
values and calculates the calibration line as follows:
Determined
values
1-point
Asy
2-point
Asy
Slp.
3-point to
Asy
5-point
Slp.
You can display the slope in the units, mV/pH or % (see section
