POINTRAC 31 • Foundation Fieldbus
41779-EN-131119
The main menu is divided into five sections with the following func-
tions:
Setup: Settings, e.g. for measurement loop name, isotope, applica-
tion, background radiation, adjustment, signal output
Display: Settings, for example language, measured value display
Diagnosis: Information, for example, of device status, peak value,
simulation
Additional adjustments: Instrument unit, reset, date/time, copying
function
Info: Instrument name, hardware and software version, date of manu-
facture, instrument features
Check if the correct language is already set 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 one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
Stick with the normal sequence of the menu items as closely as pos-
sible.
Setup
In this menu item you can adjust the POINTRAC 31 to the integrated
isotope in the source container.
For this purpose, check which isotope is integrated in the source
container. You can find this information on the type label of the source
container.
Through this selection, the sensitivity of the sensor is adapted
perfectly to the isotope. The normal reduction of the emitter activity is
hence considered through the radioactive decay.
The POINTRAC 31 requires this information of the automatic decay
compensation. This ensures an interference-free measurement over
the complete life time of the gamma emitter - an annual recalibration
is not necessary.
