6.2.5 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:
6.2.6 Calibration data
Displays the calibra-
tion data
The calibration protocol of the last calibration is available in the menu Calibra-
tion / Calibration record . To open it in the measured value display, press the
<CAL__>
key.
The calibration records of the last 10 calibrations are available in the menu Cali-
bration / Calibration data storage / Display . To open the Calibration menu in the
measured value display, press the
<OK>
key.

The calibration line is calculated by
linear regression.
You can display the slope in the units, mV/pH or % (see section

The calibration record is automatically transmitted to the interface
after calibrating.
