SAY GOODBYE TO GUESSWORK—INSTANTLY DETECT VOLTAGE POLARITY.
Component Activation
Instantly test lights, relays, motors, and power components. Car lights, fan, or relay failure? Instantly pinpoint the issue. Simply touch the wire—no stripping, bridging, or risk of blowing fuses.
Continuity Test
4-in-1 Smart Probe——Voltage, resistance, diode, and continuity—one touch for comprehensive data.
Grounding Test
Simply connect the ground wire and touch to easily test bulbs, fuses, grounding status, and plug polarity—no disassembly required.
Short Circuit Track
Use the metal probe of the circuit tester to check the circuit surface point by point. When the fault point is found, the indicator light will light up
Quickly Fix Trailer Troubles
The fastest solution for testing trailer circuits, lights, and grounding.

OPERATING PARAMETERS
Power supply: 12V battery or DC 12V
Rated input voltage: 6-24V DC
Limit input voltage: 6-30V DC
Measured voltage range: 0-80V DC
Pulse frequency counting range: 1HZ-100KHz
Overload protection: 8A

Short Circuit Track
Just check the circuit surface point by point through this circuit probe tester metal probe, when the fault point is found, the indicator light will light up

Super-Easy Component Activation
Just refer to the easy diagrams for your vehicle's components activation

Quickly Test Circuit Voltage Polarity
Instantly detect positive and negative terminals—no waiting required—to reduce repair time.
