MultiWave
This facility enables the entry of one or two equations so that post measurement
calculations can be done automatically and the end result displayed. This is a very
useful for the busy industrial, QC or environmental testing laboratory as the method
can be saved. Up to 9 absorbances at different wavelengths can be measured and 9
factors applied to them; an overall dilution factor can be applied to the completed
equation. Before entry, write the equation out in front of you; a worked example is
shown in the Appendix.
Set up
•
Enter the wavelength
•
Enter the first wavelength
•
Enter subsequent wavelengths
•
Enter the integration time using

•
Default is 0.1 second, other options are 1, 2 and 5 seconds. Use long
integration times for very low and very high absorbance readings.
Factors
•
Enter the overall dilution factor, C

Enter subsequent factors
Equation 1 and Equation 2
Enter the equation(s) to be applied to the sample measurement. If only one equation
is required, enter it and then go to equation 2 in order to save it as a method.
•
