Calibration Factor Calculations
1. Use the mean value for each parameter from the CD MEAN file
printout and the Current Open Mode Calibration Factor printout
from step 3 (Preparing for Manual Calibration section) for the
calibration factor calculations.
2. Enter the information from step 1 on the Manual Calibration
worksheet provided at the end of this procedure to calculate the
New Open Mode Calibration Factor for each parameter as follows.

Whole Blood Calibration:
3. Referring to the New Open Mode Cal Factor from the previous step
and the Current Open Mode Cal Factor from the printout, use the
appropriate chart on the worksheet to compute the Factor %
Difference as follows:
New Open Mode Factor - Current Open Mode Factor x 100
New Open Mode Factor
= Factor % Difference
4. Enter the factor % difference for each parameter in the Manual
Calibration Criteria chart on the worksheet. The Calibration
Criteria are shown in Table6.5.
NOTE: Delete the sign of the factor % difference value before
entering it on the chart.
5. To determine which parameters require calibration, continue with
the next section.
