This is the CD of experiments and training for the Electronics & Photonics kit. IEC provides a file to introduce the user to the equipment and to explain the philosophy of the design. The 9x experiment files come in 2 versions, one for the students and one for the teacher (with answers to the questions).
Although multiple experiment kits would be purchased for a class of students, only one CD is required for the whole school because all files are permitted to be copied freely.
