6.5.3 Calibration points
Excerpt from the operating menu
The following excerpt from the operating menu shows, how the density calibration points are
entered. The individual functions are explained in the sections below.
The functions are only accessible after the background calibration has been performed.
L00-FMG60xxx-05-00-00-en-015
"Calibration point" (*1A)
This function is used to select, which calibration point will be entered.
Options:
• "1" to "9" : Calibration points for various densities
• "10": recalibration point
After entering of the recalibration point, I
0
is recalculated according to the current measuring
conditions. The absorption coefficient μ is kept unchanged from the original calibration.
The calibration point "10" can be entered if the measuring conditions have changed, e.g. due to
buildup in the measuring tube.
"Calibration start stop" (*15)
This function is used to start the automatic entering of the selected calibration point.
Options:
• stop/edit This option must be selected if
– the calibration point is not to be entered (e.g. because it has already been entered). The pulse
rate of the calibration point is then displayed in the following function "density calib." (*1B).
If required, this value can be changed.
– the calibration point is to be entered manually. For this purpose, the Gammapilot M changes to
the "density calib." (*1B) function.
