Calibration record
When finishing a calibration, the new calibration values are displayed as an
informative message (symbol
i
) first. You can then decide whether to take
over these values for the new calibration or to go on using the old calibration
data. After the new calibration values have been taken over the calibration
record is displayed.

tion data and out-
put to interface
You can view the data of the last calibration on the display. Using the
<PRT>
key, you can then download the displayed calibration data to the interface, e.
g. to a printer or PC.
The calibration record of the last calibration is to be found under the menu
item,

Calibration evalua-
tion
After calibrating, the meter automatically evaluates the calibration. The
asymmetry and slope are evaluated separately. The worse evaluation of both
is taken into account. The evaluation appears on the display and in the cali-
bration record.
