6.3.1 Calibrating to a Standard
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. The instrument will calibrate to zero absorbance.
Insert a cuvette containing the standard concentration sample solution into the sample chamber and
close the instrument lid.
Press the key below the calibrate to zero absorbance or
standard icon, this will open another menu with the option
to re-calibrate to zero absorbance or to calibrate to the
previously entered standard value. Press the key adjacent
to the calibrate to standard icon.
If the standard selected requires a factor beyond the
range of the instrument the check standard icon will be
displayed.
The instrument will take a reading and calibrate to the
standard concentration. Once the calibration is complete
the sample can be measured using the measure to standard
icon.
6.3.2 Calibrating to a Factor
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. The
instrument will calibrate to zero absorbance. Once the
calibration is complete the sample can be measured using
the measure to factor icon.
6.4 SAMPLE MEASUREMENT
It is not possible to perform sample measurements before the instrument has been calibrated at the
selected wavelength. In this operating mode the type of sample measurement performed depends on
the calibration which has been carried out.
6.4.1 Measuring a Sample After Calibrating to a Standard
Remove the cuvette containing the standard sample and
place a cuvette containing the sample to be measured
in the sample chamber. Close the instrument lid and
press the key below the measure to standard icon. Once
the measurement is complete the concentration and
absorbance values are displayed.
