OTC 2-Channel Automotive Lab Scope Kit is exclusively vehicle-specific database in the 3840F and 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 features a powerful built-in reference information for each preset test: include a test procedure, normal reference signal pattern, theory of operation, and trouble shooting tips. Its extremely powerful help menu lets you find answers fast: A 25 Mega-samperele per second (one channel minimum) samperele rate for rapid data updates: true RMS GMM (Graphing Multimeter) measurements and graphs. The "Glitch Snare" feature captures, displays, and saves abnormal signal patterns in the Scope mode for component testing. The real-time comparison between actual waveforms and reference waveforms on the same screen for component testing. Its preset tests enable the user to check the majority of automotive sensors, actuators, and systems easily and quickly. 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. The USB supports fast update for code and data over the internet. The over molded case technology in the case disperses shock over more of the case than a conventional rubber boot design. It is CE-certified and has a 1 year warranty.
