If you've ever installed a Sandel 3308, you know what a complex and confusing task it is! 

Stop installing and removing components just to get it to work properly the first time. This new test box is unique - there is no other. It is a huge time and hassle saver. With it you can fully complete the system setup and test the configuration on the bench before installing in the aircraft. 

We worked with Sandel engineers to include test points for all current and proposed signals.
