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 MINITRAC 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.

With this menu item the natural background radiation can be faded
out.
Note:
Make sure that some products have a self-radiation. This is for ex-
amplethecasewithoilorpotashsaltlye.Thereforethetubemustbe

For this purpose, the MINITRAC 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(OFF).
In this menu item you can select the units of the process value and
