Records and Maintenance
Records
Article 10 CFR 35.2060 requires that an NCR licensee maintain instrument qualification records
for three years. The records must include the model and the serial number of the instrument,
the date of the qualification, the results of the qualification, and the name of the individual who
performed the qualification.
Dipper and Well Liner
Inspect the instrument on a quarterly basis to ascertain that the well liner is in place and is not
damaged. Check for contamination of the liner and dipper as follows:
1. Remove the plastic dipper and liner from the well chamber.
2. Touch <Zero Background> to zero the calibrator.
3. Replace the liner in the well chamber. If the display reading increases, the liner may be
contaminated.
4. If the liner is OK, replace the dipper in the well chamber and check for contamination.
5. If any part is contaminated, it must be decontaminated or replaced and the part must be
rechecked for contamination.
Dial Value Checks – Monthly
Each isotope button is programmed with a specific dial value (DV). The user can adjust the DV
for a particular need. Each isotope button should be checked periodically to verify it is set to
the correct dial value for that isotope. The method of displaying the dial values varies by model;
consult the operation manual for your dose calibrator to see how to display the dial values.
Note: The Dial Value check is used to verify that no one has accidently changed the Dial Value
from the factory setting or the appropriately determined facility setting.
Repair or Replacement
Consider repair or replacement if the dose calibrator falls outside the suggested tolerances.
If repair or replacement is required, contact Biodex Medical Systems, Inc. for instructions.
