This video demonstrates the correct method used to check durometer. The test part must be cured, the surface should be rigid and the dial on the gage must be positioned at zero. Once the part is properly seated on the surface, press the gage against the button at a steady rate (until the base of the gage is flush against the part). Hold in place for a moment. The red dial will display the duro from the part or button. DO NOT HOLD PARTS WHILE BEING CHECKED.
