Means/Limits Entry
1. Select a file from the QC SET UP MENU screen by using the Arrow keys on
the keyboard to move the cursor into the desired file.
2. Press [QC LIMITS] followed by [MEANS/LIMITS] to display the QC MEANS/
LIMITS ENTRY screen for the selected file [MEANS/LIMITS] and [RANGE ENTRY].
3. Use the Arrow keys on the keyboard to move the cursor to the desired entry
field.
4. Type the numbers and press the Enter key on the keyboard to save each entry
and advance the cursor to the next entry field.
5. Repeat step 4 until all entries have been made.
6. If desired, press [PRINT] to obtain a printout of the entered values.
7. Press [RETURN] to save the entries and return to the QC SET UP screen.
NOTE: When the entries are saved by pressing the [RETURN] soft key, the
software checks to see if any entries would result in a negative
number for the lower limit (e.g., mean = 1.0, limit = 2.0). If a
negative number is found, the values are automatically edited to
adjust the lower limit to zero. The bulletin line displays the
message:
LIMITS WERE CHANGED TO CORRECT OUT-OF-RANGE VALUES.
In the above example, the mean would be adjusted to 1.5 and the limit would be
adjusted to 1.5.
