The purpose of the Proof-er is to verify the operation of a displacer control without having to raise the level in the tank. This is accomplished by pulling downward on the Proof-er chain which is attached to a spring-loaded lever arm. This action lifts the displacer assembly simulating a high or high-high level condition. When the chain is released, the Proof-er returns the displacer assembly to its previous position to resume normal operation.
