Samples are placed 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
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 50mm.
The tester has a 0 to 1000 cycle per minute and may be operated in either a
"continuity" or a go/no-go mode.
