The General TechnologiesIgnition System Analyzer, No. GTC505, is compatible with all common types of spark ignition systems. The GTC505 can display waveforms in real time, compare readings between cylinders and detect and display dwell angle and primary current ramp time. Additionally, the device can chart burn time, spark plug voltage, dwell/ramp time and rpm for each spark, allowing for detection of misfires. It displays all this data on its 3.5" color TFT LCD screen. Its rechargeable Li-ion battery provides six hours of continuous use, and it passed the MIL-STD-810 drop test.
