"Avg. pulse rate" (*11)
avg. pulse rate *11
186 cps
The average pulse rate is displayed in this function (after selection of "start" in the previous function).
Initially, this value fluctuates (because of the decay statistics), but due to the integration it reaches
an average value in the course of time. The longer the averaging is performed the lower are the
remaining fluctuations.
Initially, the pulse rate strongly fluctuates. In the course of time an average value is reached.
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.
Note!
The maximum integration time is 1000 s. After this time, the value is automatically transmitted to
the "bgr. pulse rate" (*12) function.
Note!
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)
Bgr. pulse rate *12
207 cps
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 cas there are the two options:
• either return to the "background calibration" (*10) function and restart the background
calibration
• or enter a known or calculated pulse rate (manual calibration). Thereafter, the Gammapilot M
changes to the "calibr. point" (*13)or (*1A) function.
