ONYX OPERATION MANUAL
ONYX
is now monitoring radiation in your surrounding
environment and recording your measurement data to
memory (if Logging is enabled in Settings).
The CPM count is at the top of the display, with the
gamma dose rate below it, in μSv/hr or mR/hr.
When measuring surface contamination, pay attention
to CPM, rather than to μSv/hr or mR/hr.
Please note that gamma dose rate is only accurate in
situations where there is no Beta or Alpha radiation
present, or if they are shielded. The detector is not
energy-‐compensated and is calibrated to Cs137.
On the OLED display there is a colored
Status Bar
across
the top. When the bar is
Amber
, the ONYX has not yet
collected enough data to display statistically accurate
readings. Once the
Status Bar
turns blue, it is then
reading with maximum statistical relevancy.

Navigation on the ONYX is intuitive. Here is a practical
exercise.
