Tech-Scope - OTC Tools and Equipment

The OTC Tech-Scope™ Model 3857 is a versatile, professional-grade diagnostic tool designed for automotive and industrial technicians. This standalone two-channel high-speed lab and ignition oscilloscope, integrated with a digital multimeter, enables precise testing and measurement of complex electrical and electronic systems in modern vehicles. Its robust design features galvanic isolation, providing essential hardware protection during rigorous diagnostic procedures.

Key Features

• High-Speed Data Acquisition: Captures 40 million samples per second on each channel, ensuring detailed waveform analysis.
• 10 M-Ohm Input Impedance: Eliminates the need for specialized adapters, simplifying connections to critical components.
• Integrated Diagnostic Modes: Seamlessly switch between lab scope, ignition scope, and digital multimeter displays to suit various testing requirements.
• Automated Setup and Recording: Features auto-setup for vertical scale, sweep time, and trigger points, along with automatic waveform recording for up to 50 screens of data.
• Glitch and Peak Detection: Offers selectable glitch sensitivity (low, medium, high) and peak detection to capture intermittent and high-speed signals accurately.
• InfoTech Software Integration: Includes vehicle-specific repair information with step-by-step test procedures for common components, accessible via lab scope or multimeter functions.

Applications

The OTC Tech-Scope™ is an essential tool for diagnosing a wide range of automotive and industrial electrical issues. It is ideal for technicians performing engine performance diagnostics, sensor testing, injector waveform analysis, ignition system evaluation, and general circuit troubleshooting. Its capabilities extend to identifying parasitic draws, verifying signal integrity, and pinpointing intermittent faults that traditional multimeters might miss, making it suitable for both routine maintenance and advanced diagnostics on diverse vehicle systems.
