Car Parasitic Drain Tester Automotive-Electrical System Diagnostic Tool for Current Testing with U-shaped Clamp OOTDTY &nbsp ; Features: Parasitic drain tester can test the standby of the car-ECU, normal working current or abnormal working current electronic components-while the car ECU-is kept powered on, so there no need to worry about repeated testing due to loss ECU-data. Using a unique U-shaped terminals spring clip, it can be-connected to the terminals without removing the terminals cable. The car drain tester allows using standard test leads to measure the-voltage at different positions of the vehicle during the drainage test. In terms of performance, upgrade-protection also-did, which the fuse is not easy to blow & power consumption is small. Fully wrapped high-current battery-clips & low-resistance switches are used, durable & efficient. Tester is equipped with a switch-that can be turned off before connection to increase safety. The multimeter passed by the switch-during the connection process to prevent power surges. It adopts a 4mm pure-copper banana plug-that can be inserted continuously, and when using a multimeter to read the current value, it can also be superimposed on the multimeter to test the-voltage or current (compared to the multimeter). Adopt all-inclusive high-current clip to ensure smoother-operation of the product. Adopt high-current, low-resistance switch-to improve product life.
