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.
Note
You can display the slope in the units, mV/pH or % (see page 31).
The calibration procedure automatically activates the stability control
function. The current measurement with stability control can be termi-
nated at any time (accepting the current value).
The new calibration values are displayed when the calibration is fin-
ished.
You can have the data of the last calibration displayed (see page 44).
Subsequently, you can transmit the displayed calibration data to the
interface, e.g. to a PC, with the
Note
The calibration record is automatically transmitted to the interface after
calibrating.
Displayed calibration data
 Zero point = Asy
 Slope = Nernst slope
(-59.2 mV/pH at 25 °C)
 Zero point = Asy
 Slope = Slp.

The calibration line is calcu-
lated by linear regression.
