Feature: 1. Powerful Protection: The parasitic battery tester adopts in line fuses design which can protect both the meter and tester in the event a high current source on the vehicle is left on. 2. Drain Isolation: The tester and meter can keep being connected until other computer systems shut down, effectively isolating the battery drain. 3. Voltage Measurement: The parasitic battery drain tester allows measure voltage on various locations on your vehicle during the draining test with standard test leads. 4. Match to Use: Parasitic current tester can diagnose hidden battery drain with a simple method to connect a multimeter to the vehicle electrical system. 5. Universal Tester: The premium quality fuse parasitic battery tester is extensively applicable to various kinds of models, especially yours, you can purchase at ease. Specification: Item Type: Parasitic Battery Tester Material: ABS + Metal Characteristic: 1. There is no need to break the circuit to measure the current, no need to connect the power cord to test, and no need to worry about the loss of records. 2. Adopts in line fuse design, which is easy to replace without disassembly. 3. Using a pluggable 4mm pure copper rubber plug, when using the multimeter to read the current value, the multimeter can be superimposed to test the voltage or current (compared to the multimeter). 4. The unique U shaped battery pile spring clip can connect the battery pile in the case of removing the battery pile connecting line. Application: Universal. Package List: 1 x Parasitic Battery Tester1 x Manual Note: 1. Before testing the leakage, please turn off the engine and remove the key. Do not start the engine during the test to avoid burning the fuse.2. The leakage test needs to simulate the normal state that the car is not started. Please be sure to close the door, pull out the key (lockable), and make the car computer enter the sleep state.3. Different models of computers have different time to enter the sleep state. Please wait patiently when measuring to determine whether there is leakage.4. The computer standby current of different car models is different, but the ideal value should be 20‑60 mA.5. To replace the fuse of the tester, use a 10A fuse to avoid burning the multimeter.
