How do you calculate the phase to phase resistance of a transformer in the field?

I was installing a 75kVA delta-wye transformer today. I meggered the primary and secondary conductors prior to termination, terminated and took a series of resistance readings to confirm the absence of a short.

How do I calculate expected results?
 
Calculate it? You need a winding resistance test set to get an accurate reading, each phase should be about the same (few hundred milliohms)
