Cnbj 611 Tester, Parasitic Draw Tester, Automotive Fuse & Circuit Current Testers, Car Relay Fuse Blade Checker with LED Display and Light, 20a 48v High-Precision Car Circuit Probe Tool (2)

Instructions: 1. Turn off the vehicle's ignition switch. 2. Remove the blade-type fuse that comes with the tester from the socket. Then remove the vehicle fuse from the circuit to be tested and insert the tester's fuse into the electrical outlet to for ensure the correct circuit protection level. (Tester blade fuse rating: 20A/48V, standard) 3. Insert the tester's (select medium or small depending on the size of the blade fuse; if it's a small size, connect the small to the medium ) into the vehicle's fuse socket. 4. If necessary, turn on the vehicle's ignition to energize the circuit. Then, turn on the tester (press the power button) and measure the current. 5. The display will show the measured current of the circuit under test. 6. When the display shows *DC*, the circuit under test is drawing positive current. When it shows C, the circuit under test is drawing negative current. 7. After the measurement is complete, turn off the tester and press the power button again. Features: 1.
