Product Introduction
The Automotive Circuit Tester Pen is a professional circuit testing tool designed specifically for low-voltage circuit fault detection in transportation machinery. Its measurement range covers three common vehicle voltage levels: 6V, 12V, and 24V, making it widely applicable for maintenance work on automobiles, motorcycles, bulldozers, road rollers, and other transportation machinery. Precision internal circuitry paired with a highly sensitive indicator light quickly and accurately determines circuit continuity and voltage levels, helping repair technicians rapidly locate circuit faults. The portable pen-style design makes it easy to use—an essential diagnostic tool for auto electricians and vehicle emergency tool kits.

FAQ
1. Q: Can this tester pen measure AC voltage?
A: No. This tester pen is designed specifically for DC low-voltage circuits, with a measurement range of 6V-12V-24V DC. It’s mainly used for on-board circuit testing in automobiles and construction machinery, and is not suitable for testing AC voltage.
2. Q: Can it be used to test battery voltage?
A: Yes. This tester pen supports 6V, 12V, and 24V DC voltage testing. It can quickly determine whether a car or motorcycle battery has power and whether the voltage is normal. However, it cannot display specific voltage values—it only indicates circuit continuity and approximate voltage range.
3. Q: How do I use the tester pen?
A: It’s very simple: Clip the tester pen’s clamp to ground (negative), and touch the probe to the circuit being tested. If the indicator light comes on, the circuit is live and positive; if it doesn’t light up, the circuit has no power or is negative/ground.
4. Q: Which vehicle models is it suitable for?
A: It supports 6V, 12V, and 24V DC voltage, suitable for most passenger vehicles (12V), commercial vehicles (24V), motorcycles (6V/12V), and construction machinery like bulldozers and road rollers (12V/24V).
5. Q: What is the unit weight? Is it portable?
A: Only 0.05kg (50g) per unit—very lightweight. The pen-style design makes it easy to carry around, fitting in a pocket or tool bag.
6. Q: Do you support OEM branding? What’s the MOQ?
A: Yes, we support OEM/ODM customization including logo, packaging, and color options. The MOQ varies depending on the customization content. Please contact our sales team for a detailed quote.
7. Q: Is it durable? Does it break easily?
A: The housing is made of high-strength insulating material—shock-resistant and wear-resistant. The probe uses high-quality steel that resists deformation and breaking. Under normal use, it’s very durable and suitable for complex working environments like auto repair shops and construction sites.
