Gammapilot M FMG60 with FOUNDATION Fieldbus Commissioning
Endress+Hauser 83
• 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)
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 in the course of time it reaches an
average value. The longer the averaging is performed the lower are the remaining fluctuations.
L00-FMG60xxx-05-00-00-xx-023
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 "calibration" (*15) function. Select "stop/edit"
to stop the averaging procedure. The value is then automatically transmitted to the "density
calibr." (*1B) function.
!
Note!
The maximum integration time is 1000 s. After this time, the value is automatically transmitted to
the "density calibration" (*1B) function.
!
Note!
During the integration a sample of the measured material must be taken. Its density must be
determined in the laboratory.
!
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 "calibration" (*15) function. This may result
in a slight deviation between the last displayed average pulse rate and the final "density
calibration" (*1B).
"Density calibration" (*1B)
The pulse rate of the respective calibration point is displayed in this function. The displayed value
must be confirmed by pressing "E".
"-1" indicates, that no pulse rate is present yet. In this case, there are two options:
• either return to the "calibration" (*15) function and restart the calibration
• or enter a known or calculated pulse rate (manual calibration).
