Result of ORL measurement
ORL on a saturated trace
If saturation occurs during an ORL measurement, the result is given with
the sign <. This means that the actual ORL value is less than the value
displayed.
Measurement of Reflectance
It is possible to carry out a reflectance measurement of a Fresnel for a
reflective event.
Follow the following procedure to measure the reflectance:
1
Position the cursor A at the base of the peak
2
Position the cursor B at the top of the peak of the required Fresnel, or
after the peak to calculate automatically the maximum reflectance.
