OTC 3857 Tech Lab Scope

  • Part Number: OTC-3857
  • The OTC Tech-ScopeTM is a standalone two-channel high-speed lab and ignition oscilloscope with multimeter that allows service technicians to quickly and efficiently test and measure virtually all of the electrical and electronic components and circuits in a modern vehicle. The tool features galvanic isolation not found on automotive scopes for hardware protection and includes an ignition scope and a digital multimeter with an Mohm meter.
    The Tech-ScopeTM is capable of reading 40 million samples per second on each channel with 10M ohm input impedance—eliminating the need for special adapters to capture signals from critical components. The included InfoTech software provides a vehicle-specific repair information database for testing most common vehicle components with step-by-step test procedures using
    a lab scope or multimeter.
