The keys labeled 1, 2 and OTHER allow you to display activity
values for non-standard radioisotopes. The 1 and 2 keys are
programmable, eliminating the need to constantly set the
Calibration Values for any non-standard radioisotope you
constantly measure, while the OTHER key allows you to set
up the dose calibrator for a particular radioisotope at the time
of measurement (its default setting can be modified as well).
When you press any one of these keys, the
Electronic Thumbwheel (#1) Display will show the
associated Calibration Dial Value.
The Self-Test is initiated by turning the Atomlab ON, or by
pressing the TEST key. The LED on the TEST key comes
ON. Items tested include: elec trometer sensitivity, chamber
bias supply, software check sum, and the display. All LED
indicators are lit to let you know their condition. Dur ing the
Self-Test, the Activity Display does not indicate activity.
The display test sequence is as follows.
1) All segments of the numeric LEDs or digits on the Ac -
tivity Display, the decimal points, and all four Activity
Display unit LED indicators, will come ON for four
seconds. The display will look like:
8.8.8.8. µCi mCi
MBq GBq
After 4 seconds, this display will turn OFF and the next
test given in 2) will occur.
2) All Electronic Thumbwheel Display digits and decimal
points will come ON. The display will read as follows:
8.8.8.8.
3) Press the flashing ENTER key. The LED indicator on
every key will come ON.
When the Self-Test is completed and no faults have been
detected, the LED on the TEST key turns OFF. At this point,
the system is ready to use.
