10. When all runs of a sample have been completed, the bulletin line
displays the message:
NEW CAL FACTOR COMPUTED. READY FOR NEXT CAL
SPECIMEN
Press [NEXT SPECIMEN] to run the next sample.
As each run of a whole blood sample is completed, a Calibration Factor
is calculated and updated. This factor is displayed in the column labeled
<SPEC (N) FACTOR>.
The column labeled <MEAN FACTOR> contains the average of the
calibration factors for all whole blood samples used in the calibration.
The number in parentheses after mean factor indicates the number of
samples used to compute that mean factor.
The <FACTOR % DIFF> column displays the difference between the
calibration factor currently in the instrument and the mean factor
computed by the Auto-Cal program.
When all runs of all whole blood samples have been completed, the
message:
NEW CAL FACTOR COMPUTED – READY FOR ACCEPTANCE
is displayed on the bulletin line.
1. Press [PREVIOUS SPECIMEN] and/or [NEXT SPECIMEN] to
review and/or print the results of all whole blood samples that were
analyzed.
NOTE: These results are only available for review (and
printout) before the [ACCEPT MEANS] key is pressed.
2. Press [PRINT] to obtain a printout of the <SPEC> and <MEAN
FACTORS> and the <FACTOR % DIFF>.
3. Enter the factor % difference for each parameter in the Calibration
Criteria Worksheet provided at the end of this procedure. (This
worksheet may be duplicated as needed.) The Calibration Criteria
are shown in Table
NOTE: Delete the sign of the factor % difference value before
entering it on the chart.
