RT01 Automotive Relay Tester with Digital Display

Check a compatible automotive relay with a dedicated RT01 tester. A digital display and result lights bring the test process into a compact service tool.

✅ Check a relay outside the vehicle circuit - Sockets accept supported four- or five-pin relay formats.

✅ See a straightforward result indication - Green and red lights report the supported test outcome.

✅ Use a vehicle battery supply - Battery clips provide power for a correctly matched test setup.

✅ Keep test information visible - The digital display provides a local reading.

Match the Relay Before Starting a Test

The tester supports suitable general-purpose four- and five-pin relays with coil resistance of at least 20 ohms. Verify the exact pin layout and relay voltage against the instructions.

Use the specified 12 V automotive battery arrangement within the tester's stated 11-25 V detection range. Follow the connection procedure and treat the result as one part of diagnosis rather than a guarantee for every relay function.
