Figure 200: Measured signals setup – Time Stream for 7.4 hardware and below
The input time stream signals can be Enabled/Disabled by checking the
checkboxes under the “Measure” attribute. Disabling channels which are not
necessary can save memory and processing time.
The input time stream signal can also be recorded by checking the box under the
Record List against each signal. Multiple channels can be selected for recording
including the tachometer channels for a 7.5 hardware unit.
RPM Streams
RPM Streams provide the instantaneous RPM value calculated from tachometer
channel(s). This may be displayed as a time stream (versus the relative time on
the X axis).
The number of channel in this list depends on the number of enabled tachometer
channels. The following figure shows this tab’s contents when both the
tachometer channels are enabled.
