Car Relay Tester 12V with LED Indicator

Car Relay Tester 12V with LED Indicator Description

Universal 12V Car Relay Tester Automotive Electronic Relay Tester LED Indicator Light Battery Check Aoltage Tester The Importance of Relay Tester Most car lights, windshield wipers, starters, air conditioners, electric seats, electric doors and windows, anti-lock brakes and audio all use relays. Car relays are exposed to vibration, high temperature, low temperature, humidity, etc., which will reduce their service life. However, once the relay breaks down, it will immediately cause paralysis of the system components and even make the entire vehicle unusable. Therefore, it is very important to regularly check the relays inside the car. The tester will check the correct operation of the relay contacts by connecting the car battery (11V--15V) to the relay coil. Features: Car relay test tool. 1. Through the continuous car battery (11V--15V) to the relay coil, the detector can accurately check the relay contact function. 2. The tester observes the contact data, closing time, relay inertia in each test step, etc. 3. Test to correctly control the opening and closing of the relay. 4. If the relay is abnormal, the red LED lights up, it is normal for the green LED to light up. 5. Fine workmanship and good performance. 6. Easy to use. 7. Comfortable to carry. 8. Durable in use. Description: Material: Plastic & Metal Color: Black & Red Voltage: 12V Size: approx. 110 * 60 * 28mm product name: car relay tester 1 x 12V Relay Tester Five high advantages 1. Safety and environmental protection 2. Good durability 3. Cost-effective 4. Strong temperature resistance 5. Lightweight and generous Note: The car battery must be 12V battery, the voltage must be between 11-15V. The coil resistance is preferably at least 20 ohms. Please allow 0-1 cm error due to manual measurement. How to use the tool? The steps are as follows 1. Connect the power cables to the car battery -- black crocodile clip to negative pole, red crocodile clip to positive pole. 2. The tester turns on when the LED lights up RED. 3. Check the relay before connecting it to the tester. If it is a 4-pin relay, select pin 4 on the tester. If it is a 5-pin relay, select pin 5 on the tester. 4. Connect the relay to one of the three sockets. 5. Press the TEST button. 6. The tester will check the pin configuration of the unknown relay. The tester will light the RED LED if the unknown relay is not the same as most common automotive relays or if the pin on the unknown relay is damaged. 7. The tester opens and closes the relay 10 times to test the contact closing and opening time if the relay pin configuration is correct. The tester will light the RED LED immediately if the time is overtime. 8. The tester will check the consistency of the relay after testing the contact closing and opening time ten times. The tester will light the GREEN LED if the test passed, if not, the RED LED will light. 9. Disconnect the power cables from the car battery and remove the relay from the tester. It can quickly detect whether the relay is normal or not. When using a simple test, it needs to be connected to the car's 11V-15V battery. The tester will automatically detect the pin position, the action release time and the relay consistency in each test step. If the tester lights green, it means the relay is normal, and lights red, it means it is not normal. Insulation material, fine workmanship Seamless docking, more solid.
