After receiving feedback from instructors that having the spectrometer choose lambda max for the students was depriving them of an important lesson, LabQuest App now requires students to make the selection themselves. For LabQuest 2, the change is included in LabQuest App version 2.7.2 and newer and for the original LabQuest the change occurred in version 1.7.6.

Revised student instructions can be found in the 4th Edition of all the chemistry lab manuals. These instructions will work for any version of the hardware and software because no harm is done if the student chooses the lambda max on top of what the software has already chosen.
