Page 8: Principle Of Operation
When the intensity of the radiation drops below a deﬁned value, e.g. due to damping, then the POINTRAC 31 switches. The measuring principle has proven itself well under extreme conditions because it measures contactlessly from outside through the vessel wall.

Page 24: Parameter Adjustment
Check if the correct language is already adjusted for the display. If not, you can change the language in the menu item "Display/Language". Start with the setup of POINTRAC 31. In the main menu point "Setup", the individual submenu points should be selected subsequently and provided with the correct parameters to ensure the optimum adjustment of the measurement.
Page 25 This parameter is described in the operating instructions manual "Indicating and adjustment module". In this menu item you can adjust the POINTRAC 31 to the integrated Setup/Isotope isotope in the source container. For this purpose, check which isotope is integrated in the source container.
Page 26 6 Set up with the indicating and adjustment module Real value correction You can also use the POINTRAC 31 as a Slave instrument for detection of a deﬁned level. Hence you can automatically correct the measured value of a continuously measuring, radiation-based sensor to the real value when this level is reached.
