Quick Test Ring Changeover
The test fixture was designed to provide quick test ring replacement so that pre-adjusted test rings could be dropped in and used to test multiple products. A test ring holding jig is available for adjusting test rings out of fixutre for customers whith mulitple products who want to minimize fixture down time. Once a ring is a adjusted tightend and wired. You can keep it that way for as long as you need and still use the test fixture to test other products. The top and bottom test rings are removable without loosening the rings and losing the adjustments! Test ring changeover is a quick 2 minuit job. 4 screws to change the bottom ring and 4 screws to change the top ring. The top plate drops down and slides out. The bottom plate drops down and comes out the bottom panel. front and rear panel inlays with mounted connectors wired to the bottom ring will also drop inward and pull out through the bottom. This design allows everything to be removed from the test fixture as one module! The entire bottom ring and connector assemblys slide out together eliminating wiring hassels. New top and bottom test rings slide back in. We pride ourselves in our efficient designs. We emphasize our Understand-it-at-a-glance motto for intuitive easy to learn operation.
