Variable target function and erroneous data
In the X/L-J control, there are restrictions on the import of
control data into the control chart to ensure the smooth
operation of the variable target function. The specific
restriction is that control data beyond three times the range of
the control range set in advance must not be imported.
Assume that the control limits are the values given above,
with the implementation of X/L-J control. If the control data is
5.21 million, the message “Check QC Chart” will be displayed,
but the data can be entered on the chart. If the control data is
5.61 million however, it should not be entered on the QC
Chart, and the message “Reanalyze sample” will be
displayed.
Setting variable target
1. Click a parameter you wish to set in the list.
2. Click the “Variable Target” button.
The selected parameters are set for variable target. The
target column of the list is left blank for parameters set for
variable target .
Information
• When “Variable Target” is selected for quality
control, set the limits manually or read the assay
limits from the CD-ROM.
• When “C New” is selected in the Lot column,
the target and limit range cannot be changed or set
using the “Target/Limit” button (it is inactive).
Select a lot you wish to change or set: “Current” or
“New”.
