Viewing Calibration Summary
The standard deviation (all wavelengths) of the mean calibration factor
(CF) is calculated using the following equation:
The Single Wavelength tab allows you to see the results for each series of
measurements taken on the DUT on a particular wavelength.
To switch between wavelengths in the tab:
Use the up and down arrows next to the wavelength list. The tab will be
updated accordingly.
If you want to sort the columns using a particular criterion, simply click on
the header of the corresponding columns. A first click will display the list in
alphabetical order, a second click will reverse the order.
