Volume dispensed = 1 quart
Round to the nearest whole number: 163.9 =
164.
NOTE: The unit of measurement for both
volumes must be the same in the above
equation.
10. Use the UP or DOWN ARROWS to
adjust the K-FACTOR to the K-FACTOR
(Knew) calculated in Step 9.
See Table 1, page 15 for recommended fluid
