Tech-Scope oscilloscope No. 3857

The OTC Tech-Scope, No. 3857, is a standalone two-channel high-speed lab and ignition oscilloscope with multimeter that allows technicians to test and measure virtually all of the electrical and electronic components and circuits in a modern vehicle. The Tech-Scope is capable of reading 40 million samples per second on each channel with a 10 ohminput impedance-eliminating the need for special adapters to capture signals from critical components. It includes InfoTech software that 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.

InfoTech software provides easy setup instructions with functional patterns for Component and Systems tests. The OTC Tech-Scope contains "Glitch Trigger" capture that splits the screen into two: the top portion view is the live actual pattern and the bottom view is the bad pattern.
