Sound
The radiation level is indicated with a crackling sound (GM-counter like sound), which is proportional to the irradiation rate. The
sensitivity (changing frequency of the sound) is changed when the Alarm Level is changed, as described above. The sound can
be enabled/disabled from Ocean, see Measurement settings.
Trig Mode - Post Delay
When Normal measuring mode (auto-trig) is used the radiation has to be off for 3 seconds after trig off before the Scatter Probe
is ready for a new measurement. This time is called
Post Delay
. If radiation is detected before the
Post Delay
has passed, the
Scatter Probe will consider the measurement not finished, and will continue to measure.
E.g:
If an interrupt between two irradiation events is < 3 s, the Scatter Probe will consider them as one event.
If an interrupt between two irradiation events is > 3 s, the Scatter Probe will consider them as separate events.
Notice:
When the irradiation rate is low and varies, and temporarily goes below the trig level for a longer period of time than the
Post Delay
, the Scatter Probe will trig off, and a new measurement may start. In such case it is advised to use Manual
Mode (Free-run) or Timed Mode to avoid "false" trig off.
