When the value is sufficiently stable users can quit the function by pressing . After this,
the Gammapilot M changes to the "Calibration" (*15) function. Here the "Stop/edit"
option must be selected to stop the integration. The value is then automatically
transmitted to the "Density adjustment" (*1B) function.
Density calibration
• The maximum integration time (= averaging 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 then be determined (e.g. in the laboratory).
• Integration is not terminated by pressing in the "Avg. pulse rate" (*11) function.
Integration continues until "Stop/edit" is selected in the "Calibration" (*15)
function. For this reason, there may be a slight deviation between the last average
(integrated) pulse rate displayed and the final "Density calibration (*1B) .
"Density calibration" (*1B)
Local display
Density calibration *1B
1983 cps
The pulse rate of the calibration point is displayed in this function. Press to confirm the
value and complete the entry of the calibration point. If a calibration has not yet been
performed for the current point, "-1" is displayed. There are two options if this occurs:
• Either return to the
"Calibration" (*15) function and restart the calibration
• Or enter a known or calculated pulse rate (manual calibration)
"Density value" (*1C)
Local display
Density value *1C
0.9963 g/cm3
This function is used to specify the density of the calibration point. The value must be
determined from a sample in the laboratory.
The temperature effect must be taken into account when entering the density value.
The density entered must refer to the temperature at which the pulse rate has been
determined. If the density and the pulse rate have been determined at different
temperatures, the density value must be corrected accordingly before it is entered.
