Warning Levels
Select the Warning Levels function to set the alert level
for the ONYX. Once activated, the instrument will alert
with an audible tone when this level is reached. To
mute the tone, press any key. To reactivate the alert
warning mode after muting, slide the switch to Stealth
Mode(Lock) , and then back to Active Mode(Un-­‐Lock)
. To disable Alerts altogether, set the Warning Levels
to – 0 – , which is the Default Value.
If you are relying on this beeper for safety purposes, be
sure it is loud enough for you to hear it in your
measurement environment.
Bq. Eff. Value
Select the Bq. Eff. Value (Bequerel Efficiency Value)
function to pre-­‐set counting efficiency for the ONYX, so
that a reading in counts per minute may be auto-­‐
converted to Bq/cm
2
. Unless you have a need to change
this setting, and understand the ramifications, please
contact IMI before making changes to this value.
For this to be used with accuracy, the becquerel
efficiency needs to be known for the particular
radionuclide mix on the surface being measured. The
appropriate value is dependent on the radionuclide or
radionuclide mix under test. The vast majority of users
will find CPM to be the appropriate mode.
