WebSep 11, 2009 · A proving ring is a device used to measure force. It consists of an elastic ring in which the deflection of the ring when loaded along a diameter is measured by means of … WebDec 30, 2015 · PROVING RING CONSTANT. Your graph should start at the origin of the two axes. If you have zero load, you have zero deflection of the proving ring. Add load in consistent increments. For example, if you expect a total load of "X" then do increments of 0.1X. This should give you a reasonable plot of load vs. deflection of the proving ring.
