Repeat the above steps to run the sample 3 to 5 times (5 is recommended) and the analyzer
will automatically calculate the CV and calibration factor, as shows. Note that the CVs should
be within the ranges specified in Table 9-1.

The calculated calibration factors should be within the 75% to 125%. Any calculated value
that falls out of the calibration range will be flagged with a "*" at the upper right corner. Other
values will not be displayed. In case of an empty calibration factor, try to find out the reason
and if necessary, contact Mindray customer service department or your local distributor.
