The Diesel Laptops Diesel Scope Digital Storage Oscilloscope Kit is a digital storage oscilloscope (DSO) targeted towards heavy duty vehicles and equipment. The DSO allows users to see voltage readings over a period of time and presents this information as a graph. These readings can be used to diagnose electrical problems that can’t typically be seen with a multimeter or a standard diagnostic tool. The Diesel Scope offers the functionality of standard Picoscope tools, but also incorporates guided diagnostic tests specifically for medium duty and heavy duty vehicles. Diesel Scope customers receive one year of free access to wiring diagrams on Diesel Repair.
