The MST-600 is an easy to use, fully automated tool designed to verify the proper operation of Loadswitches, Flashers, and Transfer Relays that are used in traffic signal installations conforming with NEMA or CalTrans specifications.

The tester auto-detects the device plugged in at turn-on and prompts the user with a few options prior to starting a test. The MST 600 goes beyond the basic functionality tests offered by other testers, to assure specified operation within all testable standards. The tester is housed in a sturdy metal case that can be ordered for bench or rack use. A 3 button user interface provides an easy test set up without the layers of frustrating, hidden menus. Once the setup is established, the tester executes the tests and interprets the results automatically.
