I need to verify the resistance on a HV transformer that receives 208v single phase through terminal 1 and 2, or 240v through terminal 1 and 3 and delivers 4000v through terminal 4. As per the specifications, the resistance between t1 and t2 needs to be somewhere between 0.8-1.1 ohms(obvious the transformer has to be completely disconnected of power for the test). i tried a few clamp multi testers and none seemed to deliver a proper reading, some take a little long to come to a reading and oscillate up and down, bottom line is, i almost never have a proper reading. question, what multi tester (preferable a clamp style, because i need it for other applications) would be the proper one for the call. thank you very much in advance.
