Normalization, Calibration and Master Calibration
To verify a correct master calibration, perform several reference mea-
surements.
Now, it is possible to make measurements in the open Application. Delete
the readings of the reference measurement before starting with the mea-
surements on your specimens.
6.4.4 Displaying Xn Ranges for Calibration Standards for the Master
Calibration
During the master calibration, the master characteristic can be determined
only if suitable calibration standards are used.
The calibration standards are suited for the master calibration only if their
normalized countrates Xn are within pre-established Xn ranges. They can
be queried during the master calibration without affecting the calibration.
Please note the information regarding the number of calibration standards
under 6.4 on Page 70.

BLOCK-RES Use BLOCK-RES to display the Xn range
for calibration standard #1.
[0.0300<Xn<0.2500]: The normalized
countrates Xn of calibration standard #1
must be within these limits of the Xn range.
BLOCK-RES Use BLOCK-RES to display the Xn range
for calibration standard #2
[0.3000<Xn<0.7000].
