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: "Level",

"Point level" or "Summation Slave".

The natural radiation on earth inuences the accuracy of the meas-

urement.

With this menu item the natural background radiation can be faded

out.

For this purpose, the POINTRAC 31 measures the natural back-

ground 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.

In this menu item you can select the temperature unit.

in this menu item you can select if you want to carry out a single or

double point adjustment on the sensor.

With the double point adjustment, the Delta I value is selected auto-

matically.

We recommend selecting the double point adjustment. To use this,

you must be able to change the level of the vessel so as to carry out

the adjustment of the sensor with full status (covered) and with empty

status (uncovered).

Hence, you will get a very reliable switching point.

With single point adjustment, you have to dene the dierence

between the min. and max. adjustment points (Delta I) yourself during

the following setup.
