You are not following the instructions correctly. You are supposed to detune the secondary (bottom) then adjust the primary (top) for maximum. Then to proceed to adjust the bottom not for minimum but for zero. The VTVM needle will swing positive and negative. You must adjust for zero.
I do not understand why you want to null out both primary and secondary? That is not how a Foster-Seeley discriminator works.
