5.2.6 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:
Calibration
1-point
2-point
3-point to 5-
point
You can display the slope in the units, mV/pH or % (see section

5.2.7 Calibration data

The calibration record is automatically transmitted to the interface
after calibrating.
The calibration record of the last calibration is available in the menu Calibration
/ Calibration record. To open it in the measured value display, press the

key.
The calibration records of the last 10 calibrations are available in the menu Cali-
bration / Calibration data storage. To open the Calibration menu in the
measured value display, press the
