5 In the List by WL and List by Power displays, use the
the reference values (wavelength and power values of each laser line before the test
was started).
During the measurement, you can change the display mode to Peak WL, List by WL,
List by Power, or Avg WL. When List by WL or List by Power is selected, the signal
list is sorted by reference values and not by the current, maximum, or minimum val-
ues.
To restart the drift measurements, press RESET. This resets the reference values.
wavelength and smallest power measured. The laser line of
interest may have since drifted to a greater value. Note that the
minimum wavelength and minimum power may not have
occurred simultaneously.
Display shows the total drift from the reference since the drift
measurement was started. Values represent the minimum
wavelength and power drift values subtracted from the
maximum drift values.
