#2 CURSO DE REPARACION DE CELULARES: ¿Qué HERRAMIENTAS necesito? | Herramientas de DIAGNÓSTICO 2/7 🔧

Okay, let's start with the diagnostic tools. First, and this falls into the super fundamental category. I can't be a cell phone technician if I don't have this tool. And in this case, look, I have it painted back there, which is our friend the multimeter, or tester, whatever you want to call it. Obviously, it comes with a

Okay, there are manual range testers that are a bit better; they have a larger screen and a little stand on the back to keep it propped up for tech enthusiasts. Okay, that depends on everyone's budget. Second, our friend, the power supply, or

adjustable power supply, also called a laboratory power supply. And here's the big question: what's such a thing for? Now I'll tell you. It's called a power supply.
