Page 6: Principles Of Operation
Use of bichromatic differential absorbance values corrects for optical imperfections in the plastic wells, differences in well meniscus, turbidity, and lamp variation. A photo detector converts transmitted light energy into electrical signals, which are amplified and interpreted. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 8: Safety Precautions
The instrument should be surrounded by the following clearances: 8 cm around perimeter of unit and 8 cm on top. Do Not Operate Without Covers Do not operate this instrument with covers and panels removed. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 10: Installation

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. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 20: Selecting A Strip Format
You may change between reading 8 well strips and 12 well strips via the ALT key whenever the display indicates “Ready”. If a test is stored in the test menu, the strip type will also be saved. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 21: Selecting A Mode
It also checks the individual control wells or the means for QC purposes. The user may select Correction factor and equivocal range options. These adjust the cutoff value to determine cutoff points for interpretation of subsequent specimens. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 22: Quitting A Mode
CLEAR key twice to cancel the mode, and then begin again with the primary wavelength. Your choices will be printed, and the operating mode will resume. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 23: Selecting A Blank
For calculating the standard curve, n=3, n6. If one well of a pair is deleted during an editing cycle, then the other well will represent the mean point and n=3, n2 and n5. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 24: Unit Codes
In Point to Point and Multipoint % Abs modes, you may also choose to flag samples having absorbance values higher than the highest calibrator or lower than the lowest calibrator. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 25: Selecting Control Options
“H”, “L”, or no flag are used to indicate high, low, or in range respectively. If your test is stored, the locations and acceptance criteria of the controls entered will also be stored for later recall. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 26: Selecting An End Location
Over bar in determine instrument carrier position. Ensure that these holes are not blocked or obscured by 12-Way Carrier 8-Way Carrier markings on (STANDARD) (OPTIONAL) the end of strip tabs. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 27: Calculation Programs
Load the first strip into the right-most carrier position and press ENTER. While the strip is being automatically positioned for reading, the display will indicate “Positioning Strp”. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 28: Cutoff Mode
If X*mNC is less than the Min C/O, the Min C/O will be used as the cutoff. The display will prompt “Min C/O =”. Enter the minimum cutoff value. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. - Page 29 Error messages will also print in the Interpretation column: H - indicates that the blank or the individual control exceeded the limit entered. L - indicates that the individual control was lower than the limit entered. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J...
-
Page 30: Cutoff Control Mode (C/O Control)

Page 40: Calibration And Linearity
A monthly verification of instrument calibration and linearity is recommended. Such monitoring can be done using DRI-DYE Check Strips ® . There is more information about DRI-DYE Check Strips ® in the Appendix. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 41: Additional Tips And Information
Use clean strips and follow the instructions for blanking and standardizing very closely. (Use of the appropriate blanking material is also very important...water alone is not always specified.) Do not read wells with bubbles or condensation. Awareness Technology, Inc. Stat Fax 303 Plus Operator’s Manual Rev. J... -
Page 42: Maintenance
Be careful not to soak liquids up under the keyboard overlay. If this happens, simply allow the keyboard to dry before resuming operation. Such a spill does not present a hazard, but may cause temporary malfunction of the keys. Stat Fax 303 Plus Operator’s Manual Rev. J Awareness Technology, Inc. -
Page 43: Troubleshooting
Be certain that reagents are dispensed into the correct wells. Refer to the operating instructions for each mode regarding correct placement of the blank and calibrator materials.
