Operation
Samples are pleased in an upright position by six rollers with the mandrels
moving vertically between the rollers, subjecting the upper sample surface
to tensile strains on the upward stroke. The samples are held in precise
position relative to the mandrels by a weight, which also serves to assure
conformance of the sample to the mandrel curvature.
This weight, 250g for circuits and 100g for foils, subjects the samples
to non-zero mean tensile stresses which are small enough to be insignificant.
The mandrels are high accuracy rods having diameters ranging from 0.5 to
30mm.
The tester has a 0 to 1000 cycle per minute and may be operated in either
a "continuity" or a go/no-go mode.
Manufactured in the U.S.A. by the makers of the most complete line of
toroid winding machines in the world.
