RANGE SELECTION
The Atomlab Dose Calibrator automatically selects the prop-
er range to display the activity results (either mCi or µCi if
you have selected Ci, or GBq or MBq if you have selected
Bq). The selection is made on the basis of providing maxi-
mum resolution for the number displayed. Therefore, all you
have to do is place the source in the Chamber Well and
read the activity value from the Activity Display.
ISOTOPE SELECTION
Isotope selection can be done at any time before or after
placing the source into the Chamber Well. As soon as you
press an Isotope Selection key, the displayed activity value
is corrected in accordance with the corresponding
Calibration Value stored in memory.
DISPLAY UNITS
Proper units for radioactivity can be either the traditional
Curie (Ci) or the international unit Becquerel (Bq), whichev-
er may be required in your facility. Your Atomlab Dose
Calibrator has the ability to display in either system by user
selection through the SETUP key.
To change the Atomlab 100 Display Units, press the SETUP
key and observe its LED come ON. This indicates the
Atomlab 100 is in Setup mode. Observe that the unit indica-
tor to the right of the Activity Display (for example, µCi) is
blinking at the same rate as the LED on the OTHER key.
Press the OTHER key and see that the other system of units
(MBq) is now displayed and the displayed activity value has
been corrected in accordance with this new system of units.
If you removed your Check Source, place it back into the
Chamber Well. Toggle the units back and forth by pressing
the OTHER key. Before leaving Setup mode, ensure that you
have selected the proper system of units and then press the
SETUP key again. This will lock the units selection into the
display. The Activity Display units can be subsequently rese-
lected in the Setup mode.
