Multifunction testing device

Battery test Battery energy test 1. Please remove all other connections from the battery and leave it for at least 15 minutes before testing. 2. Connect the red wire to the positive wire and the black wire to the negative terminal of the battery. 3. Read the indicators, and they will show the current battery energy. 4. If only the battery energy indicator (green) lights up, it indicates that the battery is too low for the car. If no indicator lights up, the battery may be empty or not properly connected to the tester. Battery condition test 1. Please fully charge the battery before testing. 2. Connect the red wire to the positive terminal and the black wire to the negative terminal of the battery. 3. Turn the car key to ACC, and operate as many car functions as possible (for example, lights, radio, etc.) for about 3 minutes, then observe the indicator. 4. If there is any problem, the "battery energy" indicator will turn off. If the battery is good, * the battery energy will stay "green. Warning: • Do not perform the battery condition test for more than 6 minutes. Please stop the test once the green "battery energy" light turns off. • A poor battery condition is not the only reason for the "battery energy" to turn off; it can also be caused by other faults such as alternator issues or short circuits, etc. Alternator test To start the test, the user needs to connect the tester to the battery, then start the engine, and operate as many car functions as possible (for example, lights, radio, etc.). Let the engine run at its lowest capacity.
