The MODIS, VERUS, and Vantage Pro have a dedicated ignition trigger input that does not display the trigger signal, this can put you at a disadvantage. Snap-on scopes have an internal trigger, why do I need an external trigger?

The AES Trigger Pickup (Inductive) Lead is an 'external trigger' and connects to any scope channel, usually channel 1. Use the AES Trigger Pickup signal to mark fire in the hole - #1. The Trigger Pickup signal will represent #1 compression in the cranking compression waveform.Įxhaust Pressure Testing: Same as above.

To step through the crank signal, move the Trigger Pickup to the next plug wire…and the waveform will update a new section of the signal!Ĭranking Compression: Place the AES Trigger Pickup on #1 spark plug and perform a cranking compression test.

Put the AES Trigger Pickup on #1 plug and trigger from it. This results in a signal that walks left and right across the screen. Stepping through the Crank Signal: Many crank signals are very repetitive without any specific characteristic to trigger from. The pulse produced by the trigger pickup makes this possible. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.ĭisplaying a trigger signal on the screen is a very powerful aid for signal analysis, whether you need to judge the relationship of a signal to a position of the crank shaft or to an ignition event, or simply, just to hold/stabliize a repetitive signal. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. arsenic and chromium from chemically treated lumber.crystalline silica from bricks and cement and other masonry products, and.WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.
