Car Test Pen DC Test Pen Car Vehicle Repair and Repair Test Pen 6V / 12V / 24V Universal

1. The test range is 6V-12V-24V (do not use beyond the test range), 2. Length 133mm, light volume, pointed design (with a pen tip), compact structure, easy to carry and use. 3. Automobile test pencil is specially designed to detect the low voltage circuit failure of transportation machinery, which can be used in the maintenance operations of transportation machinery such as automobiles, motorcycles, bulldozers, rollers and so on. 4. Product features (LED bulb): 1. When the test head touches the positive pole of the car, the red LED glows, indicating that the line you are pointing to is the positive pole. 2. When the test head touches the negative pole of the car, the blue LED glows, indicating that the line you are pointing to is the negative pole. 3. The difference of the measured voltage will not cause the obvious difference of the brightness and darkness of the light-emitting tube and the soft light, which will not cause too much irritation to the eyes, especially for the staff working in a dark environment Under the car), the damage to the eyes is smaller, and the working efficiency is increased, and with the increase of the measured voltage volts, the brightness of the bulb will not change much, thereby increasing the life of the bulb; while the ordinary bulb With the difference of the measured voltage, there are obvious differences in the brightness of the light-emitting tube. The higher the measured voltage volts, the brighter the bulb, the easier it is to burn out. 4. Remarks: There are two types of bulbs: ordinary bulb and LED bulb. 5. Weight 0.055 kg
