Products > Diagnostics

Automotive On-board diagnostic systems of these days have gone a long way toward helping you locate a problem. But those systems aren't perfect and they don't cover everything (most glitches and intermittent). So the real challenge that befuddles most automotive technicians is diagnosing "no-code" trouble. On-board diagnostic systems are engineered with fairly wide set limits for sensors, actuators, connectors and terminals. When a component exceeds its limit consistently, a trouble code is generated. But to keep warranty costs in line, tolerances aren't set to catch all transients, even though they can cause some of your worst headaches. As a result, technicians are finding more and more uses for the oscilloscope - next to the multimeter, the most common troubleshooting tool.

The V-Scope represents the most powerful and versatile tool available for troubleshooting automotive electronics since we can track down elusive no-code driveability problems.
A 25 Mega-sample/Second (one channel minimum) sample rate for rapid data updates.
Lab scope signal patterns.
True RMS Graphing Multimeter (GMM) measurements and graphs.
A unique "Glitch Snare" mode which captures, displays and optionally saves abnormal signal patterns in the Scope mode of the COMPONENT TESTS only when they occur.
Preset tests that enable the user to check the majority of automotive sensors, actuators and systems easily and quickly.
Powerful built-in reference information for each preset test which includes a test procedure showing how to connect to the circuit, a normal reference signal pattern, theory of operation and troubleshooting tips.
Menu-driven interface has automatic configurations for most of non-preset tests, so you will find that the instrument is easy-to-use.
The Secondary Ignition Single function displays the waveform along with the spark voltage, RPM, burn time and burn voltage.
The Diesel function allows you to set injection pump timing and RPM using the optional Diesel accessories.
USB interface supports updates for code and data.
