Peak to Peak spectral repeatability Follow
Question: What does it mean maximum peak to peak 0.20 between 435nm and 695nm on the UltraScan Pro specifications?
HunterLab uses the term "peak-to-peak" to represent the maximum range for a consecutive group of 20 readings of the Instrument Standard White tile. Configure EasyMatch QC to take 20 timed readings at 10 second intervals. When the readings are complete then for each wavelength between from 435nm to 695nm calculate the peak-to-peak. Using the group of 20 readings, subtract the minimum %R or %T reading from the Maximum %R or %T reading and report the difference. If the difference is above 0.20 then the instrument may need adjustment.
