Display calibration data
and output to interface
You can have the data of the last calibration displayed (see section
4.7.8). 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.
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 and
in the calibration record.
