Features: • The exclusive vehicle-specific database in the No. 3840 contains information for most domestic vehicles, as well as many imports. The scope also recommends the appropriate test procedures for fast, accurate repairs. Visible on the screen are diagrams showing pin numbers and wire colors for both the PCM and the component connector. • 2-channel lab scope. • A 25 MHz sample rate per channel for rapid data updates. • True RMS GMM (Graphing Multimeter) measurements and graphs. • A unique “Glitch Snare” feature captures, displays, and optionally saves abnormal signal patterns in the Scope mode for component testing. • Real-time comparison between actual waveforms and reference waveforms on the same screen for component testing. • Preset tests 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 includes a test procedure, a normal reference signal pattern, theory of operation, and troubleshooting tips. • The extremely powerful Help Menu lets you find answers fast. • The secondary ignition single function displays the waveform along with the spark voltage, RPM, burn time, and burn voltage at the same time. • The diesel function allows you to set injection pump timing and rpm using the optional diesel accessories. • USB interface supports update for code and data over the internet. • Over-molded case technology disperses shock over more of the case than a conventional rubber boot design. • Kit includes red and yellow test leads, black ground lead, 3- and 5-way alligator clips, 3 test probes, 3 back probes, ignition probes, inductive pickup, lead extensions, AC adapter, update cable/software, soft carrying case, and user manual.
