About this item
①Intelligent automatic detection: With just one push of a button, the device automatically detects the type of 12V/24V relay. OBDResource relay tester supports 4 different pin configurations (4-pin/5-pin), shows the relay status (opening/closing) and the function in real time, allows quick error localisation and does not require manual configuration.
②Wireless, portable design: Car relay tester is simply powered by the battery terminals and does not require an external power source. this makes it ideal for mobile testing outdoors or in the workshop and overcomes the limits of conventional stationary test equipment.
Wide compatibility: Automatic voltage detection covers over 20 common automotive relay types, is compatible with 12V/24V voltage and various pin arrangements (4pin/5pin) and is suitable for both home use and professional repairs - without problems caused by incompatible devices or relays.
Safety and gentle testing: thanks to non-invasive test technology, the internal relay circuit is not damaged. he device accurately detects the status of opening/closing relays and ensures a safe and reliable test process.
Warning instructions for use: OBDResource relay tester relay detection clearly indicates that the battery voltage (12 V or 24 V) must fit for testing to avoid errors due to incorrect voltage. it only supports 4 pin configurations and reminds users of correct handling to ensure accuracy.
⑥Usage Process: The red battery clip must be clamped to the positive pole of the battery and the black battery clip to the negative pole of the battery. at this point, the LED lamp indicates red. insert the relay into the corresponding connectors, select the appropriate pin and press "Test" to perform the test. (If the voltage of the tested battery is lower than the voltage of the relay, the LED will remain red. in this case, a higher voltage should be used for the test.)
