MemoryPointeroptionmakesurethe
pointer is returned to zero before starting.
2. Press the foot of the gauge firmly
against the specimen, but not so
firmly as to imbed the foot into the
surface of the material.
3. Maintainpressurefor2to3seconds. 
The dial hand gives the reading in
durometer points.
IMPORTANT: After the initial reading has been noted, continue
maintaining pressure for several more seconds. Creep or cold-flow of the
specimen, if present, will be evident by receding action of the dial hand.
4. Repeat above steps for each use.
An example of a properly noted durometer reading:
“Durometer A 61, Creep 7 at 15 seconds, 73°F.”
