Gammapilot M FMG60 PROFIBUS PA Commissioning
Endress+Hauser 43
A0018118
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).
"Background pulse rate" (*12)
Local display
Backgr. pulse rate *12
186 cps
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.
6.5.3 Full and empty calibration or covered and free calibration
Excerpt from the operating menu
The following excerpt from the operating menu illustrates the procedure for empty and full
calibration (for level measurements) or for free and covered calibration (for point level
detection). The individual functions are explained in detail in the sections that follow. The
functions are only accessible once the background calibration has been performed.
