I'm just trying to figure out how to use my fancy LCR meter. All I want to do is measure the impedance of a 1:1 audio transformer and compare against the data sheet.
Data sheet says impedance should be 15K with a 600 ohm load but the LCR is spitting out 3.2k. I have bought the handheld DE-5000 to verify the first LCR but ability meters agree.
All I have to do is hook a 600ohm load up to the secondary, right? I'm totally confused

The test current put out by the analyzer is likely not enough get the iron core fully involved in the reading, resulting in less perceived inductance.
"If I have a transformer whose turns ratio is 1:1 , and I connect a 600 ohm resistor across the secondary , in this condition what is the impedance looking into the primary?"
If I had any engineer friends I probably would have asked them in the first place. None the less, I'm guessing due to impedance reflection, the 1:1 ratio and a 600 ohm resistor across the secondary the primary impedance would be about 600 ohm? If that is the case, why did the Datasheet say 15K?
