Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J 15
2.0 OPERATING PROCEDURES
When reading microstrips, the instrument must be programmed to calculate and to label wells
and results according to the operator’s specifications. For test procedures with many entries, it is
recommended that inexperienced operators prepare a list of their selections before beginning
operation.
Alternately, these tests can be stored in non-volatile memory to reduce set up requirements to a
single step for subsequent uses. When tests are recalled from the user menu, all of the general
selections will have been predetermined. Section 2.1 provides information about making general
selections such as mode, filter, blank, duplicates, cutoffs, and controls. Section 2.2 follows with
mode-specific instructions for each of the general purpose calculation programs. Section 2.3
explains how to create and use your own test menu (stored in nonvolatile memory). Finally,
Section 2.4 provides specific details on the operation of additional special features (i.e. clock and
calendar, lamp saver, etc.).
2.1 General Selections
Although many features are available to aid the user, this instrument may be operated very
simply in most modes by bypassing optional features.
For every test, the instrument will require a mode selection and filter choices. Thereafter, only
those questions that pertain to the calculation mode selected will be asked. In the absorbance
mode, for example, there are no further selections required.
Here is a list of questions to review before beginning a test:
1. What strip length will be used? (8 wells or 12 wells)
2. What strip type will be used? (e.g., break apart)
3. What calculating program will be used?
4. What filters are optimal? (operating and differential wavelengths)
5. Is a blank required? Desired?
6. What is the calibrator value(s)?
7. Will blanks, calibrators and/or specimens be read singly, or in duplicate?
8. Will locations of 1 or more controls be marked? If so, you will need to indicate row and strip
number for each.
9. Will control acceptance criteria be entered for automatic comparison? If so, what are the
limits?
10. Will a cutoff value be used to label any samples as positive? (If so, the value which begins
the positive range will be required.)
11. Will a cutoff value be used to indicate negative samples or define an equivocal zone? If so,
results less than what cutoff should be labeled as negative?
12. Will you be running partial strips? If so, you may want to assign an END location.
