5.2.6 Calibration data
Displaying the cali-
bration data
The calibration record of the last calibration is to be found under the menu item,
<ENTER> / Calibration / Calibration record . To open it, press the <CAL__> key
in the measured value display.
Subsequently, you can transmit the displayed calibration data to the interface,
e.g. to a PC, with the
<F2> [USB output] key.
Displaying the cali-
bration data storage
The calibration records of the last calibrations (up to 10) are given in the menu,
<ENTER> / Calibration / Calibration data storage .
Determined
values Displayed calibration data
1-point Asy  Zero point = Asy
 Slope = Nernst slope
(-59.2 mV/pH at 25 °C)
2-point Asy
Slp.  Zero point = Asy
 Slope = Slp.
3-point to
5-point Asy
Slp.  Zero point = Asy
 Slope = Slp.
The calibration line is calculated by lin-
ear regression.
You can display the slope in the units, mV/pH or % (see section
8.1.1 S

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