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. Package: 1*RT01 Relay Detector Attention: 1.The car battery must be a 12V battery, and the voltage of the battery must be between 11V and 25V. 2.The applicable coil resistance should preferably be above 20Ω.
