Smart circuit tester, 0.8V-100V DC voltage tester with backlight, digital test lamp with flashlight, voltage tester pen for cars and trucks

1. Multifunctional Inspection: Circuit testing is ideal for checking various vehicle circuits, quickly verifying car headlights, taillights, signal circuits, faulty receptacles, connections, and testing other wires and DC circuits. 2. Safe and Burn-Proof: The professional automotive circuit tester has an integrated circuit chip, which is safer and more durable than traditional test lamps, preventing the car's computer board from burning out. 3. Bidirectional Testing: This upgraded circuit test lamp is a bidirectional voltage tester. You can attach the clamp/holder to a negative or positive ground. 4. Effective Protection: The integrated structure design of the probe's protective cover is adopted, and the needle sleeve function is added to ensure there will be no injury or loss of protective equipment. 5. Portable and Convenient: Easy to carry anytime, anywhere, used for circuit testing, supports DC Voltage 2V, 20V, 100V. SPEC: Item Type: Automotive Test Light Model: HT86A Material: ABS Battery: 1 x 1.5V AAA battery (not included) Purpose: Circuit testing Basic Parameters: DC Voltage: 2V, 20V, 100V; Resistance: 2000Ω, 20kΩ, 200kΩ, 2mΩ, 20mΩ Instructions: This measurement mode is used by default when the system starts. In this mode, DC and OFF voltages can be measured, and the instrument automatically recognizes the measurement signal. 1) Press the power button to turn on the instrument; the instrument will display "-" to indicate intelligent measurement mode. 2) Touch the probe of the pen to both ends of the signal being measured (in parallel), and the instrument will automatically identify the signal being measured. 3) During measurement, the buzzer will sound when the value is less than approximately 50Ω. 4) Read the measurement results from the display. Packing list: 1 x Meter, 1 x Storage bag, 1 x User manual
