I found this old transformer from an old tube tv, is 120v input and about 140v output, so i can build myself an Isolation Transformer,and i'm trying to know how many amps does it put out, i already blew a fuse out on my Fluke 88V by measuring the same way we measure volts with the AC A setting, is there another way to measure amps , i never studed it deeply because never had to use the amps side, do i have to use some resistor in series with it,can you explain it to me, also how to know which is the hot and the neutral of the secondary side of the transformer because measure one side is 140+v, and reverse probes and have same 140+v, compared to the primary that measure one side 123+v on the hot side, and reversing probes get ov on the neutral side.
Hi, Me again Correct me if i'm wrong I may take this as an exemple, I have a RCA TV and i connect it to the transformer that i mentioned that i wanted to know how to measure amps in its output,and to use it as an isolation, to repair the tv for circuit protection,
OK Now i plugg the tv power cord in the transformer, and i unsolder the black wire (the hot) that is soldered in the hot side of the CHASSIS and connect it to the COM black lead of the meter, and the positive +lead to the Chassis side where the hot black wire was soldered before,after i set the meter for amps settings, now i plugg power cord of the tranformer in the wall out let, now is this the way to measure amps , forgive me if i'm slow to understand how things works, but have no JD i am portuguese emigrant in the USA, i took an electronic correspondence course, i've been studying by myself electronics for a long time, what is very dificult to learn besides i have not a chance to get my hands on the job, besides a few tvs and stereo stuff that i got to learn on my own ,and read the books as you see, to learn this way is tough. Thanks again for you time and patience.
