The average pulse rate is displayed in this function. Initially, this value fluctuates (because of
the decay statistics), but reaches an average value over time due to integration. The longer the
averaging is performed, the lower the fluctuations.

When the value is sufficiently stable users can quit the function by pressing
. After this, the
Gammapilot M changes to the "Background calibration" (*10) function. Here the "Stop/
edit" option must be selected to stop the integration. The value is then automatically
transmitted to the "Background pulse rate" (*12) function.
Background pulse rate
• The maximum integration time (= averaging time) is 1000 s. After this time, the value
is automatically transmitted to the "Background pulse rate" (*1B) function.
• Integration is not terminated by pressing in the "Avg. pulse rate" (*11) function.
Integration continues until "Stop/edit" is selected in the "Background calibration"
(*10) function. For this reason, there may be a slight deviation between the last
average (integrated) pulse rate displayed and the final "Background pulse rate"
(*12).

The pulse rate of the background calibration is displayed in this function. Press to confirm
the value and complete the background calibration. If a background calibration has not yet
been performed, "-1" is displayed. There are two options if this occurs:
• Return to the "Background calibration" (*10) function and restart the background calibration
• Enter a known or calculated pulse rate (manual calibration). The Gammapilot M then
changes to the "Calibration point" (*13) or (*1A) function.
