Improperly crimped connections result in failures and therefore loss of wins. In order to be sure your crimp tool is properly crimping terminals, you need to periodically check that it is within spec. Normal usage can result in the indent teeth no longer meeting this spec through tooth wear or internal mechanism wear. This gage allows you to quickly determine if your crimper is within spec, simply set your crimper to the appropriate setting and fully close the indent teeth. With the indent teeth fully closed, attempt to run the green and red sides of this tool through them. The green side should be able to pass through, but the red side should not.
