bration data

The calibration record of the last calibration is to be found under the menu item,

the <CAL

_> key.

The calibration records of the last 10 calibrations are to be found in the menu,

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

linear regression.

You can display the slope in the units, mV/pH or % (see section

9.1.1 S

ETTINGS FOR PH MEASUREMENTS, page 61).

The calibration record is automatically transmitted to the interface

after calibrating.
