blank value. If you select yes for the cell blank, the test is necessary. Put blank samples in each cell before
test, the system will record the measurement values of each cell automatically.
If you select “yes” for both reagent blank and cell blank, you can perform cell blank for each cell and
take the sample in No.1 cell as the blank to correct the measured values of other cells.
Blank correction is a kind of data processing. The following table shows the calculation.
