Select "Linearization - New"toenterthefirstpoint.
Select "Determine count rate"toenterthefirstpoint.
The determination of the actual count rate lasts 2 minutes. After the
count rate has been determined, you can accept the value (ct/s).
The count rate is stated in ct/s. This is the number of counts per second, i.e. the measured radioactive radiation dose actually reaching
the sensor.
Enter now the corresponding level (m).
By doing so, you assign a respective level to the actual count rate.
Accept the value pair with "OK".

If you have a non-linear vessel (e.g. spherical tank), you have to carry
out this adjustment with as many points as possible.
A maximum of 32 linearisation points is possible.
