1. Can quickly detect whether your relay is normal, easy to use, suitable for automotive relays on the market, support 12V and 24V relay testing2. Most car lights, wipers, starters, air conditioners, electric seats, electric doors and windows, anti-lock brakes and audio use relays. Automotive relays are subject to vibration, high temperature, low temperature, humidity, etc., which will reduce their lifespan. However, once a relay fails, it will immediately cause system components to be paralyzed, and even cause the entire aircraft to be unusable. Therefore, it is very important to regularly check the relays in the car3. Through the continuous car battery to the relay coil, the detector can normally check the contact function of the relay4. The tester observes the contact data, closing time, relay inertia, etc. at each test stage5. Easy to operate, easy to carry, and durableOperation instructions:1. When testing, clamp the red clip to the positive pole of the battery and the black clip to the negative pole of the battery2. When testing a 12V relay, it needs to be connected to a 12V battery3. After connecting to the power supply, the device lights up red and the relay can be inserted4. To test the 4-pin relay, turn the switch to 4PIN, and to test the 5-pin relay, turn the switch to 5PIN5. After connecting the relay and adjusting the pin position switch, you can press the button6. If the pin position is incorrect or the relay is damaged during the test, the red LED light will be on7. When the pin position is set correctly, the tester will light up the green LED light and flash 10 times to indicate that the relay is normalSpecification: Package Weight One Package Weight 0.26kgs / 0.58lb One Package Size 19cm * 16cm * 4cm / 7.48inch * 6.3inch * 1.57inch Qty per Carton 32 Carton Weight 9.50kgs / 20.94lb Carton Size 40cm * 34cm * 34cm / 15.75inch * 13.39inch * 13.39inch Loading Container 20GP: 576 cartons * 32 pcs = 18432 pcs40HQ: 1338 cartons * 32 pcs = 42816 pcs
