To measure an order track
This task shows you how to use calibrated transducers to measure order tracks. Before
you complete this task, however, you may want to measure order spectra to help you
identify the orders you want to track. Both of these order-mode measurements are
possible only if your analyzer is equipped with Option 1D0.
1 Initialize the analyzer.
