What do non-traditional career paths look like?
I wouldn't worry about tunning a loop system because Automation technicians do that. As an instrument tech I would definantly want to know about basic physics and basic circuit knowledge. I do agree with Rusty Nash on knowing something about open and close loops, understanding how a DCS works is good to know too As you gain experience in this field you will eventually become an Automation tech,if you show interest in it.
As for certificate? I don't know of any training or certifications other than "on the job training" or getting an AAS in Engineering Technology with an emphasis in Electrical. I would suggest going the 2 year route of school because this field is hot.
