Displaying the
calibration data
You can display the data of the last calibration (see page 36).
Subsequently, you can transmit the displayed calibration data to the
interface, e. g. to a printer or PC, with the
_
> key.
Note
The calibration record is automatically transmitted to the interface after
calibrating.
Sample record:
Calibration evaluation After calibrating, the meter automatically evaluates the calibration. The
zero point and slope are evaluated separately. The worse evaluation of
both is taken into account. The evaluation appears on the display as
the CalClock and in the calibration record.
