Calibration
The calibration must be performed at the same wavelength at which the sample will be measured. Insert a cuvette
containing the blank solution into the sample chamber and close the instrument lid. Touch the
icon. This sets
the instrument to zero absorbance and 100% transmittance.

Sample Measurement
It is not possible to measure a sample before the instrument has been calibrated at the selected wavelength. Once
the calibration has been performed the Sample icon becomes active and a sample can be measured. Remove the
cuvette containing the blank solution and place a cuvette containing the sample to be measured in the sample
holder. Close the instrument lid and touch the
icon.
