Ignition Scope

Ignition Scope Setup

To display secondary ignition waveforms the Lab Scope must be properly configured to the type of ignition system you are testing, and for the type of display pattern you wish to view. For general reference information on ignition waveforms, see Ignition Waveform Reference .

Typical Secondary Ignition Signal

1. To start the setup process, select Scope Multimeter from the Home screen.
2. Select Ignition Scope.
3. Choose one of the following test modes:
Parade - displays the secondary waveform pattern for each cylinder in the firing order from left to right across the screen.
Cylinder - displays the secondary waveform pattern for the selected cylinder.
Raster - displays the secondary waveform pattern for each cylinder in the firing order, from the bottom to the top across the screen.
Superimposed - displays the secondary waveform pattern for each cylinder in the firing order stacked on top of each other.
Single Cylinder Ignition - configures the unit to connect to an individual cylinder using a fixed time sweep when a lead is not available to connect to all cylinders.
4. Select Setup from the upper toolbar.

The Ignition Scope Preferences menu opens. From this menu and the sub-menus within it, you can configure all the settings needed to display secondary ignition pattens.

5. From the Preferences menu select Setup .

6. From the sub-menu select Ignition .

The main ignition setup menu opens.

7. Choose an ignition system Type, there are four types of ignition system choices available.

The basic setup of each Type, are described in the following sections.
