The Pro50™ Digital Irrigation System Tester is a complete tool for testing multi-wire electrically-controlled irrigation systems – verifying controller functions, wiring continuity, and valve solenoid operation. It is designed for users who may need to test both conventional AC systems and DC (9-volt battery) operating systems. In the AC mode, the tester measures and activates valve circuits using 24 volts, while in the DC mode the tester uses the same signals as popular 9-volt battery-operated controllers to activate DC latching solenoids. The Pro50™ will “chatter” valves in both modes. It includes a built-in auto-ranging multimeter that will read voltage up to 40 volts and resistance up to 40 kilohms. The standard electrical test leads are interchangeable with the test leads from your other meters if you want to probe terminals and wires instead of clipping on with the alligators.
