5.2.6 Calibration data
Displays the calibra-
tion 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 memory
The calibration records of the last calibrations are to be found in the menu,
<ENTER> / Calibration / Calibration data storage.

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
9.1.1 S
ETTINGS FOR PH MEASUREMENTS, page 50).
The calibration record is automatically transmitted to the interface
after calibrating.
