Bombaywalla,
My scale IS rather magnetic so here's what I do. I put the scale beneath the arm but down on the TT stand next to my plinth. (On a Teres the tonearm hangs out over the stand.)
This puts the scale the height of the Teres below the tonearm, about 8" or so. I put a little homemade paper tower on the scale with the plastic weighing tray that came with the scale on top. The tower puts the tray at record height and keeps the cartridge 8" or so above the scale.
YMMV depending on the design of your plinth. Another way to do it is to make a jig like the Wally scale comes with. One guy on VA made one from a broken CD jewel case. (Good use for that, ay?)
