New automotive Tech-Scope allows fast electrical testing

Global developer and manufacturer of advanced diagnostic systems SPX Service Solutionshas launched the OTC Tech-Scope, which will allow service technicians to 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 anda digital multimeter with an ohm meter.

The Tech-Scope is based on a proven hardware and software solution developed exclusively by SPX’s OTC brand. It is capable of reading 40 million samples per second on each channel with a 10 ohm input impedance, which the company says eliminates 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 also provides set-up instructions with functional patterns for component and systems tests; by selecting a specific type of component to test, the unit will set up the correct time base and voltage range. The device also 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.

The device also boasts a help menu to assist the user in finding answers quickly, with real-time comparison between actual waveforms and reference waveforms on the same screen. Built-in reference information for each preset test include a test procedure, normal reference signal pattern, theory of operation and trouble shooting tips, enabling the user to check the majority of automotive sensors, actuators and systems quickly and easily, SPX says.
