When a new measurement is started, only those traces will be displayed on the screen in the
Measure tab (
Section 8.2 Measure Tab
). Any previous traces can be accessed via the Traces
tab (

) until the unit is switched off. Upon completion, the view will initially
default to the selected test mode viewing screen (V-Scout, Event (Auto), or Measure (Manual).
If multiple wavelengths are selected in the
Setup
menu, the measurement will be performed
using all selected wavelengths one after another without stopping and will be overlaid on the
screen for comparison and review. V-Scout traces are overlaid and displayed automatically.
