Determination of the Normalized Countrate Xn of a Cal-
ibration Standard During a Master Calibration
The normalized countrate Xn of a calibration standard can be determined
as described below during a master calibration without affecting the cali-
bration.
fe.
Mean value of all readings obtained for this step of the
calibration.
s
Standard deviation of the readings obtained for this step
of the calibration.
Because
FINAL-RES
triggers an externally triggered measurement acqui-
sition if external start is enabled, is not possible to determine the normal-
ized countrate if external start is enabled during a calibration!

Press
FINAL-RES
to start the procedure.
Calibration stan-
dard
Place the probe whose normalized count-
rate Xn shall is to be determined on the cali-
bration standard. The normalized countrate
Xn of the calibration standard will be dis-
played (the normalized countrate will not
be stored!).

: Use
FINAL-RES
to re-
turn the free-running display mode to the
disabled state.
It is now possible to continue the calibra-
tion.
