following values and calculates the calibration line as follows:
Note
You can display the slope in the units, mV/pH or % (see page 28).
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 the calibration is fin-
ished.
Display calibration data
and output to interface
You can have the data of the last calibration displayed (see page 42).
Subsequently, you can transmit the displayed calibration data to the
interface, e.g. to a PC, with the
<F2>
/
[USB output]
key.
Note
The calibration record is automatically transmitted to the interface after
calibrating.
