TAKING A DRIFT TEST
With the gauge still in an area free of other nuclear gauges or
radioactive sources and on the reference standard block, press
〈1〉 at
the Drift Test menu shown above.
NOTE
If it has been less than four hours or more than eight
hours since the last stat test, then the gauge allows the
operator to exit the drift test. To exit and take another
stat test, press the
〈YES〉 key at the prompt. To continue
with the drift test, press the

The gauge prompts the operator to place the gauge on the reference
standard block with the source rod in the SAFE (shielded) position.
Ensure that the gauge is positioned properly and press the
〈ENTER〉
key.
The gauge displays the progress of the drift test. After taking the
drift test, the gauge displays the average counts and indicates if the
test passed or failed. If it fails, see page C–3
for instructions. Press
the
〈ENTER〉 key to return to the Drift Test menu, or press the
〈ESC〉 key to return to the Ready screen.
