5.3 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. Press the
key below the calibrate to zero absorbance icon. This
sets the instrument to zero absorbance and 100%
transmittance.
Once the calibration is complete the measure sample icon appears and the sample can be measured.
If the wavelength is adjusted before a sample is measured the measure sample icon will disappear
and the instrument must be calibrated again at the new wavelength.
5.4
SAMPLE MEASURMENT
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 measure sample icon is displayed 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 press the key below the
measure sample icon. Once the measurement is complete the photometric result will be shown on
the screen.
Subsequent samples can be measured in the same way. If the wavelength is adjusted between
sample measurements then the instrument must be calibrated again before more samples can be
measured.
