It can also be used with other equipment such as printers that have 12V electrical systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What current range does this battery leakage detector measure?\u003c\/h4\u003e\n\u003cp\u003eA: The tool measures standby and parasitic current starting from 30 mA. For most common vehicles, the ideal standby current is between 20–50 mA. If the display reads 0, it indicates no detectable current leakage. The included 10A fuse protects the unit during measurement.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this detector while the engine is running?\u003c\/h4\u003e\n\u003cp\u003eA: No — you must turn off the engine and remove the key before using this battery leakage detector. Running the engine during testing may damage the built-in fuse. Always wait for the vehicle to fully enter sleep mode before taking a reading for the most accurate results.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the relay testing function do?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in relay tester with digital voltage display allows you to quickly identify faulty or failing relays in your vehicle's electrical system.
