Stability control 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).
Calibration record When finishing a calibration, the new calibration values are first dis-
played as an informative message. Then you can decide whether you
want to take over these values of the new calibration or whether you
want to continue measuring with the old calibration data. After accept-
ing the new calibration values the calibration record is displayed.
Display of calibration

You can display the data of the last calibration (see page 166). Subse-
quently, you can transmit the displayed calibration data to the interface,
e. g. to a printer or PC, with the
<PRINT> key.
Sample record:
Note
You can display the slope in the unit, mV/pH or % (see page 73).
Note
The calibration record is automatically transmitted to the interface
after calibrating.
