Backgr. cal. *10
Stop/edit
Start
This function is used to start the background calibration
Options:
• Stop/edit
This option must be selected if:
– No background calibration is to be performed but the pulse rate of an existing background
calibration is to be displayed instead.
– The background calibration is to be performed manually.
Once this option has been selected, the Gammapilot M goes to the "Bgr. pulse rate"
(*12) function where the existing pulse rate is displayed and can be changed if required.
• Start
This option is used to start automatic background calibration. The Gammapilot M changes
to the "Avg. pulse rate" (*11) function
"Avg. pulse rate" (*11)
Local display
Avg. pulse rate *11
186 cps
The average (integrated) pulse rate is displayed in this function (after the selection of "Start" in
the previous 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.
