Scanner Viewing and Saving Data (PIDs)

6.4.8 Using Zoom
The zoom function allows you to change the magnification level of the
graphed data during data collection and review. Changing magnification
levels allows you to compress or expand the displayed data to quickly
find glitches, or signal losses.
When the Zoom icon is selected the dropdown menu allows you to select the display
magnification level from a range of -2X to +8X. The "Zoom Out" option displays up to
half of the maximum amount of data that can be collected, on one screen. The default
magnification level is 1x.
Examples: Top (+4X), Middle (1X), Bottom (Zoom Out)

6.4.9 Using Triggers
Trigger Description and Features
Setting PID triggers allows you to configure the diagnostic tool to
automatically save PID data to a file, when a PID value meets an upper/
lower limit (trigger point).
When a PID value meets the trigger point it activates the trigger which
captures a short recording of all available PID data and saves it as a data file.
You can review the saved data file to closely evaluate not only the PID that triggered
the event, but all the PIDs being monitored to collectively see what was happening at
the time of the event.
Examples of the following trigger states (Armed / Not Activated - upper image) and
(Activated - lower image) are shown in (Figure 6-38).
