I'm building my test/repair bench (I'm a hobbyist). I've been reading and watching videos on needing a isolation transformer to protect test equipment (oscilloscope) , and the tester (me). I'm wanting to know that best route to take. Should I get a single output isolation transformer or a Variac that has isolation built in (i've provided some links below)?
Also, I've read that you want to put the UUD (Unit Under Test) on the isolation transformer and NOT your oscilloscope. If anyone can direct me to references to this fact, I'd appreciate it.
