APOLLO-D8 Training Module 5

Applies To: APOLLO-D8™

Scanner Data Graphing View: Views, PID Triggers, Cursors, Cause and Effect, Zoom, Save



Snap-on Training Solutions® helps you get the most out of your SOLUS Edge™ diagnostic tool. This training module covers the use of scanner data in graphing view.


A numeric view of Parameter ID, or PID data, will not always reveal problems and or show relationships between PIDs.

Graphing relationships between data parameters gives you a view of performance over time.

Data graphing can show momentary failures and data trends over time.

The View icon switches the live data viewing mode between a numeric view and a graphing display. From one to four graphs can be displayed on the screen.

The graph provides a large number of data points plotted so you can compare events over time. Multiple graphs allow you to view relationships between components. Values to the left of each graph show the current, maximum and minimum value of captured data. Minimum and maximum values are stored even after the data has scrolled off-screen.


You can choose data parameters you want to see together on one screen. Just highlight any parameter and select the lock icon to lock it on the top of the screen.

Scroll down and lock to select additional parameters. This enables you to see relationships between data parameters. Simply select the lock icon again to unlock a parameter.

Up to 3 data PIDs can be clocked at one time. You can scroll through the data below while the locked PIDs stay on top.

The Zoom icon incrementally increases and decreases the scale of the data being displayed.

Tap the zoom icon and select a plus level to zoom in for more detail.

Select a minus level to zoom out and see more data.


The PID Trigger is a valuable tool to automatically capture data when a parameter value is outside of normal range.

The Set Trigger command sets upper and lower values to start recording a data movie when the signal crosses the set value similar to an OBD-II freeze-frame. To set a trigger, select the data parameter you want to use. Then tap the Trigger button and select Set Trigger from the drop-down menu.

Tap the plus and minus buttons on the toolbar, or use the up and down arrow buttons to position the upper trigger line to the desired level.

Tap the checkmark on the toolbar, or press the Yes button, to accept the value.

The lower trigger level line will appear on the graph. Position the line to the desired level.

Tap the checkmark on the toolbar to accept the lower trigger value.

The trigger points will appear as horizontal lines across the designated parameter graph. Triggers can be set on up to three parameters at once.

To arm, the triggers, tap the PID Trigger button on the toolbar and select Arm Triggers from the drop-down menu.

The trigger lines on the data graphs change color; a blue outlined flag appears to indicate an armed condition, any data point outside of your set conditions pauses the data collection saving a recording.

Once triggering is armed, it remains on until you clear or disarm.

Once the trigger point is passed, the tool will beep and the flag will turn red, indicating that the PID has exceeded the parameters that were set.

The tool will record additional data, then save it. The gray line shows where the recording was saved.

The recorded data movie is automatically saved. Tap the Previous Vehicles & Data icon on the home screen and select View Saved Data to review the movie.

Select the movie file you wish to view.

Use the scroll buttons to scroll forward or back through the collected data.

Saved recordings can also be reviewed in ShopStream-Connect, free computer software which is available to download from diagnostics.snapon.com/SSC.

Select “Clear All Triggers” to clear the trigger values.
