The symbol [SB] appears at top left corner of the screen and stays here and will remain
all the time that this option is selected or that the operator did not leave the analysis in progress
or the mode of concentration measurement.
- Insert the first sample blank and run the measurement by pressing <START ENTER> key.
As for the blank, the operator can reject measurement (F2 key [Discard]) or make several times the

- Press F4 key [Apply] to run the sample measurement. It displays:
- Insert the sample corresponding to the measured sample blank and start the measurement by pressing
<START ENTER> key. It displays:
It displays the sample absorbance read against the zero (i.e.: 0.630) and the sample concentration
calculated as following:
Sample concentration = sample absorbance read against the zero minus sample blank absorbance
read against the zero multiply by the factors or calculated according to the calibration curve.
