Parameter Customisation - Final Setup
The 'tick' icon was pressed to access the waveform
display.
The PDU was now ready to start recording data.
The 'record' icon was selected to start recording data.
When the fault occurred, the ABS warning lamp
automatically triggered the PDU. This will place a fixed
cursor on the screen and set the time base to zero. The
PDU will stop recording after the preset record time. If no
record time has been entered, the PDU w i l l use its default
record time of 16minutes and 40 seconds. 8m20s pre-
trigger and 8m20s post trigger.
The following figure indicates the typical waveform display
for the wheel speed sensor fault. The dotted vertical line
represents the trigger point.
