Make Relay Checks More Straightforward

Bring a dedicated tester to compatible automotive relay checks. The ANENG RT01 combines four- and five-pin relay testing with a digital display and clear indicator lights, helping you work through the check with one purpose-made tool.

Key Benefits

• Four- and five-pin support — Test compatible general-purpose relay formats.
• Digital display — Keep the tester’s voltage reading visible.
• Red and green indicators — Read the result using the indicated test status.

Keep the RT01 with your automotive diagnostic tools for a more organized relay-testing routine. It connects to the vehicle battery supply and should be used with relays that meet its stated requirements.

Relay Detector 11-25V ANENG RT01 Digital Universal 4/5 Pins Car Battery Vehicle Detection Digital Display Voltage Battery Tester

Introduce:
RT01 can quickly detect whether your relay is normal.It is easy to use and suitable for general-purpose automotive relays on the market.Durng testing, it needs to be connected to a 11V-25V battery in the car. The tester will automatically detect the foot position,the time of action release, and the consistency of the relay in each test stage. lf the tester turns on the green LED light, it means that the relay is normal; if the red LED light is on, it means that the relay is not normal.

Specification:
Product Model:RT01 Relay Detector
Applicable pins:5 pins/4 pins
Battery detection:11V~ 25V voltage
Applicable coil resistance:≥20Ω
Use power:Connect car battery power supply
Detection prompt light:lf the tester turns on the green LED light, it means that the relay is normal; if the red LED light is on, it means that the relay is not normal.
Alligator clip opening size:2.1cm/0.82inch
Alligator clip length:42cm/16.54inch
Digital display bright screen:Yes

Operating instructions:
1）Clip the alligator clip of the tester on the car battery the black clip on the negative electrode and the red clip on the positive electrode.
2）When the red LED light is on, it indicates that the tester can start testing.
3）Check the relay before testing.  lf it is 4 feet, choose a 4-foot socket on the tester;  if it is 5 feet, choose a 5-foot socket on the tester.
4）Plug the relay into one of the three sockets
5）Press the "Test" button
6）The tester will automatically detect the pin position of the unknown relay. When the relay is not a universal relay on the market or is damaged, the tester will turn on a red LED light.
7）When the foot position is set correctly, the tester will open and close 10 times to detect the release time of the action. When the detection time is too long, the tester wil light up the red LED light.
8）When the tester has detected the action release time 10 times, start to detect the consistency of the relay. When the test is OK, turn on the green light, and if the test is not OK, turn on the red light.
9）After the test is complete, remove the alligator clip from the battery and remove the relay from the tester.
