The P150 is engineered to simplify the complex electrical architecture of modern vehicles. It features a crisp 1.77-inch TFT color display that provides immediate numerical feedback, removing the guesswork from how to use automotive circuit tester devices in high-stakes repair environments. From tracing short circuits to measuring the duty cycle of a cooling fan, the P150 provides the clinical data needed for a first-time fix.

Professional Diagnostic Intelligence

• Comprehensive Signal Analysis: Beyond simple voltage (0.1–70V), the P150 measures Frequency (10Hz–200kHz) and Duty Cycle (1–99%). This is essential for testing modern computer-controlled components like fuel injectors and electronic throttles.

• Smart Component Activation: Safely power up components directly from the probe. The P150 is built for heavy-duty use, supporting an 8A continuous load and peaks of up to 16A, allowing you to verify motors and lights instantly.

• Precision Resistance & Diode Testing: Identify high-resistance connections (0.1Ω–200kΩ) and verify diode health (0.2V–2.6V) without needing a separate multimeter.

• Short-Circuit Location & Ground Inspection: Quickly trace and locate hidden shorts or poor ground points that cause intermittent electrical gremlins.

• Injector Signal Detection: A dedicated mode for monitoring fuel injector pulses, helping you isolate mechanical fuel issues from electrical command faults.

Safety & Rugged Design

• Multi-Stage Circuit Protection: The P150 features an intelligent internal breaker that manages current thresholds (8A/12A/16A) to protect the tool and the vehicle's sensitive ECU during component activation.

• High-Visibility Interface: The 160×128 resolution color screen ensures that voltage readings and waveforms are clearly legible in dark engine bays or bright sunlight.

• Ergonomic Portability: At just 0.322 kg and encased in a durable ABS housing, the P150 is designed for the daily vibration and impact of a professional workshop.

• Battery-Powered Simplicity: Draws power directly from the vehicle's battery, ensuring it is always ready to work whenever the hood is up.
