22. Set the nominal buffer value for the measured temperature with
< >< >.
23. Accept the calibration value with <ENTER>.
The calibration display for the next buffer appears (voltage display).
24. If necessary, use <M> to finish the calibration.
The calibration record is displayed.
or
Continue calibrating using the next buffer with <ENTER>.
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.

5.2.5 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:
Calibration
1-point
2-point
3-point to 5-
point
You can display the slope in the units, mV/pH or % (see section

5.2.6 Calibration data

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