The calibration of bulk cone measurements switching at a certain
bulk cone diameter is described on page 62.
Note!
As an alternative to code 39, you may also use - in the profes-
sional mode - the bulk density function in code 35.

Input Interference radiation detection
0 Disabled
1 Enabled
This function detects interference radiation if the live count rate
exceeds the empty count rate in code 30 by a factor of 1.5. If in-
terference radiation has been detected, the measurement is
stopped for at least the length of the waiting time defined in code
41. For further information see page 64.
