In this menu item you can adjust the SOLITRAC 31 to the isotope
installed in the source container.
For this purpose, check which isotope is 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 per-
fectly to the isotope. The normal reduction of source activity through
radioactive decay is thus taken into account.
The SOLITRAC 31 requires this information for the automatic decay
compensation. This ensures error-free measurement over the entire
lifetime of the gamma emitter - an annual recalibration is not neces-
sary.
Enter the requested parameters via the appropriate keys, save your
settings with
[OK]
and jump to the next menu item with the
[ESC]
and
the
[->]
key.
Enter here, the respective application.
This menu item enables adaptation of the sensor to the requested ap-
plication. You can choose between the following applications: "

Summation Secondary
".
The natural radiation on earth influences the accuracy of the meas-
urement.
With this menu item the natural background radiation can be faded
out.
For this purpose, the SOLITRAC 31 measures the natural background
radiation and sets the pulse rate to zero.
In the future, the pulse rate from this background radiation will be
automatically deducted from the total pulse rate. This means: only
the component of the pulse rate originating from the source will be
displayed.
The source container must be closed for this setting.
