No idea what "ring out" means.
It depends on how many leads and the winding configuration of the transformer. More information would help answer your question.Transformers since the phases and neutral all connect together in the windings ,then when you set a meter on ring/ohm it should ring out when you go phase to phase or phase to ground/neutral right?
I meant in reference to testing a transformer, never heard of someone ringing out a transfrormer.
Depends on what you are testing for. I test doorbell transformers for open circuit all the time with simple continuity testers. If open circuit test fails on a transformer like this there is no point in doing any other testing it needs replaced.
Sorry what I meant to say was continuity on a fluke meter. When you get continuity on a fluke while set on ohms it will ring and that was what I meant .let me explain my problem. we are installing the service and everything else that go after in a 250k sq ft building .we had to set 3 208/120 transformers for general purpose like offices after the 480 service , my boss comes in and puts the fluke on the secondary side of the trans and it shows continuity between phase to phase /phase to ground. I tell him it?s because the winding are connected and that?s why he is getting continuity( there?s no service voltage yet if wondering)then he puts the meter to the panel the secondary is connected to , and says there?s a short so I open the ocd and show him the panel phases are not grounded and that he was getting back feed through the winding .well I was not going to argue with him and he even started making me second guess myself .so here I am asking you guys question that I already know .so if you understand where I?m coming from set it in stone for me.
