Note
You can display the slope in the units, mV/pH or % (see section 4.6.3).
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 The new calibration values are displayed when a calibration procedure
is completed.
Display calibration data
and output to interface
You can have the data of the last calibration displayed (see section
4.6.8). Subsequently, you can transmit the displayed calibration data to
the interface, e. g. to a PC, with the <PRT> key.
Note
The calibration record is automatically transmitted to the interface after
calibrating.
