To be honest I do not remember any difference in testing with a meter. Ge has a lower forward drop but that did not affect this type of testing.

I had an old analog meter with a transistor tester that could test static/differential Beta which was of some interest but not much....it was all listed in datasheets.


The diode, if one of them is open, could affect the centerpoint by about 1V. If shorted - by about 0.4V.
