"Avg. pulse rate" (*11)

If the value is sufficiently stable, the function can be left by pressing "E".
Thereafter, the Gammapilot M changes to the "backgr. calib." (*10) function. Select "stop/
edit" to stop the averaging procedure. The value is then automatically transmitted to the
"bgr. pulse rate" (*12) function.
NOTICE
Bgr. Pulse rate
‣
The maximum integration time is 1000 s. After this time, the value is automatically
transmitted to the "bgr. pulse rate" (*1B) function.
‣
The integration is not terminated by pressing "E" in the "avg. pulse rate" (*11) function.
It is continued until the selection of "stop/edit" in the "backgr. calib." (*10) function.
This may result in a slight deviation between the last displayed average pulse rate and
the final "bgr. pulse rate" (*12) .
"Background pulse rate" (*12)
On-site display Meaning
Avg. pulse rate *11 The average pulse rate is displayed in this function (after selec-
tion of "start" in the previous function). Initially, this value fluc-
tuates (because of the decay statistics), but due to the integra-
tion it reaches an average value in the course of time. The
longer the averaging is performed the lower are the remaining
fluctuations.

" E "
On-site display Meaning
Backgr. pulse rate *12 The pulse rate of the background calibration is displayed in this
function. By pressing "E" the displayed value can be confirmed
and the background calibration completed.
"-1" indicates, that
no background calibration is present yet. In this case there are
two options:
• Either return to the
"background calibration" (*10) func-
tion and restart the background calibration
• Or enter a known or calculated pulse rate (manual calibra-
tion). Thereafter, the Gammapilot M changes to the "calibr.
point" (*13) or (*1A) function.
