Note
Below the smallest value, the calibration curve is extended to the zero
point and, above the largest value, it is extended to the end of the
measuring range.
Note
The entry of calibration values that exceed the measuring range leads
to a calibration error. The size of the measuring range is dependent on
the selected measuring mode (matrix type) (see section 3.5.3).
Entering the Calibration
data
Note
For examples of valid value pair data, see section 4.2.2. A maximum of
8 value pairs can be entered for the User calibration.
8
Sort the value pairs in descending order and, if necessary,
enter them in a table and diagram (see chapter 10).
9
Check the form of the calibration curve.
If the calibration curve corresponds to form 3,
change the conditions at the measuring location and
determine the calibration values again or
do not carry out any measurements in the range below the
turning point (A).
10
In measuring mode with matrix type 1:
If individual calibration values lie outside the measuring range,
change the conditions at the measuring location and
determine the calibration values again or
select measuring mode for matrix type 2
