"Calibration start stop" (*15)
Options:
• stop/edit
This option must be selected if
– the calibration point is not to be entered (e.g. because it has already been entered). The
pulse rate of the calibration point is then displayed in the following function "density
calib." (*1B) . If required, this value can be changed.
– the calibration is to be entered manually. For this purpose, the Gammapilot M changes
to the "density calib." (*1B) function .
• start
This option is used to start the automatic entering of the calibration point. The
Gammapilot M then changes to the "avg. pulse rate" (*11) function.
"Avg. pulse rate" (*11)
A0018118
If the value is sufficiently stable, the function can be left by pressing "E".
Thereafter, the Gammapilot M changes to the "calibration" (*15) function. Select "stop/
edit" to stop the averaging procedure. The value is then automatically transmitted to the
"density calibr." (*1B) function.
NOTICE
Density calibration
‣
The maximum integration time is 1000 s. After this time, the value is automatically
transmitted to the "density calibration" (*1B) function.
‣
During the integration a sample of the measured material must be taken. Its density must
be determined in the laboratory).
‣
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 "calibration" (*15) function. This
may result in a slight deviation between the last displayed average pulse rate and the
final "density calibration" (*1B) .

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 in the course of
time it reaches an average value. The longer the averaging is
performed the lower are the remaining flucuations.
