The Lang Tools Dual Channel Automotive Scope, No. 13805, is an automotive scope and graphing digital multimeter with dual-channel capabilities. It has a sample rate of 20 mega-samples per second, 48 pre-set waveforms, DC to 5 MHz bandwidth, and a sweep rate of 1 microsecond to 50 seconds in 'scope' mode. The "Glitch Snare" mode saves irregular patterns to catch intermittent failures. Secondary ignition functionality displays the waveform with spark voltage, RPM, burn-time and burn voltage. A built-in "Help" shows users how to connect to the circuit, a sample of the expected waveform, theory of operation and troubleshooting tips.
