Trace Tab
This displays the diagnostic traces from the sensor when the trace button is
activated or when replaying a saved file.
The vertical axis is related to the signal strength, while the horizontal axis is related
to the detected flow.
When a signal is received, the ‘ green square indicator
’ will move down from 10
on the vertical axis. The further the ‘ green square indicator
’ moves from 10, the
larger the strength of the received signal. During flow condition, the ‘ green
square indicator
’ will normally be within the range of 30 to 70. Under no-flow
conditions the ‘ green square indicator
’ will remain at 10.
When flow is detected, the ‘ red circle indicator
’ will move horizontally to
indicate flow detection. The ‘ red circle indicator
’ should stay at 0 under no-flow
conditions, and move along the horizontal axis when flow is detected.
Under flow condition, the line should still approach and flatten out at just below
the signal index 10 line.
If the trace remains flat or the indicators struggle to remain stable during flow,
then increase the ‘Gain’ (P102) setting.
You are also able to see the current velocity measurement obtained by the sensor
in the chosen volume and time units selected.
