If any question: please contact first.Feature:Can quickly detect whether your relay is normal, simple to use, suitable for the market of automotive relays, support 12V and 24V relay test. For testing, the device needs to be connected to a 12v car battery. When testing, turn the switch to 4PIN or 5PIN according to the pin position of the relay. After pressing the test button, the tester lights up with a green LED light and blinks, indicating that the relay is normal. If the test button is pressed, the red LED light indicates that the relay is abnormal.1. When testing, clip the red clip to the positive electrode of the battery and the black clip to the negative electrode of the battery2. When testing the 12V relay, connect it to the 12V battery.3. If the indicator is red after the power supply is connected, you can insert the relay4. Test 4-pin relay Switch to 4-pin and test5 pin relay Turn the switch to 5 pin. 5. After the access relay adjusts the pin switch, you can press the button6. When the foot position is wrong or the relay is damaged during the test, the red LED light will be lit during the test.7. When the foot position is set correctly, the tester will light a green LED light and blink green for 10 times, indicating that the relay is normal.How to use the tool?1. Connect the power leads to the car battery --black alligator clip to negative terminal, red alligator clip to positive terminal.2. Tester is powered up when the LED illuminates in RED.3. Check the relay before plugging into the tester. If it's a 4 pin relay,select"4 pin" on the tester.If it's a 5 pin relay, select"5 pin"on the tester.4. Plug in the relay into one of the three receptacles.5. Press the "TEST" button.6. Tester will check the pin configuration of the unknown relay. Tester will light the RED LED if the unkonwn relay is not the same to the most of common automotive relaysor the pin of the unknown relay is destroyed.7.Tester will open and close the relay 10 times for testing the time to contacts closure and opening if the pin configuration of the relay is right. Tester will light the RED LED immediately if the time is overtime.8. Tester will check the consistency of the relay after testing the time to contacts closure and opening ten times. Tester will light the GREEN LED if the test passed, if not light the RED LED.9. Disconnect power leads from the car battery and remove relay from the tester.Product Description:Test voltage 12vPackage List:1x Relay TesterABS
