6.7 Changing QC Ranges
QC ranges can be set and changed when operating in the Preset Mode. The QC Mode is set in
the [QC Common] screen to preset, cumulative, or none.
1. Select [Parameters], [QC Control], [QC Specific].
2. Use function key F8 (test no.) to get to a specific test number, or use the pull-down menu
located next to the test name field.
3. Press function key F4 (set) then function key F5 (edit). Enter the new QC average
(mean), standard deviation (SD), and range at the fields. The average is listed on the
package insert. The range (2SD above and 2SD below the mean) is listed on the package
insert. Type in the entire value of the range. The SD (1SD) is the range divided by 4.
4. Press the “Close” button and select function key F2 (exit) to set the new ranges.
5. Optional: Select function key F3 (print) to print a list of the new mean, SD, and range.
Example: The Beckman Coulter Control package insert lists the mean as 120, and the range as
115 to 125. You would type in 120 as the mean, 10 as the range and 2.5 as the SD.
