The certification program is the base of the integrity triangle.  All installers should fully understand the equipment they will be using and how to calibrate it. They should know how to properly install the DS-3 line and how to test it. Trompeter provides certified trainers to teach all aspects of this process and upon successful completion of the program, the trainee earns a “Trompeter Certified Installer” certificate. For information on how to become a certified Trompeter installer, contact a local Trompeter sales representative or a DigiKey customer service representative.
