If interference radiation is detected, the following sequence starts
automatically:

Flow chart
interference radiation
If interference radiation is detected, the
measurement goes to the HALT mode.
- Reading and current output are
"held".
- Error relay indicates alarm.
The measurement is stopped until the
defined waiting time is over.
Once the waiting time in code 41 is
over, the program checks if the count
rate is smaller than 1.5-times the empty
count rate (Io).
If not, the waiting time is started again.
If the count rate is below 1.5-times the
empty count rate, the measurement
automatically goes to the RUN mode.
