Maintenance and troubleshooting 79
Accessing the waveform display
You access the waveform display from the Diagnostics menu by selecting around which point along the
waveform you want to center your main marker.
• To access the waveform display, select Diagnostics > Waveform > [desired centering location]. (At
Sensor Ref. Point, At Level, At Interface, At Distance, or At End of Probe).
Selecting a level/interface echo
Once you have accessed the waveform display, you can browse through and select various echoes, and
see their respective distances.
Obtaining the distance for the current level or interface
The current distance displays the measured distance between the reference point and the level. This
feature allows you to select another echo as the level echo (previous or next) and confirm that the
measured distance matches the real distance.
To select the current distance:
1 Select Diagnostics >Waveform > Level Echo Selection or Interface Echo Selection > Current
Distance.
The distance of the current level or interface echo appears.
2 Press Back.
Selecting another echo
To select the previous or next echo measured on the probe:
1 Select Diagnostics > Waveform > Level Echo Selection or Interface Echo Selection > Select
Previous Echo or Select Next Echo.
2 Press OK. The chosen echo is selected.
3 Press Back.
4 Select Current Distance to verify that this is the echo that you wanted to select. If not, repeat steps 1
to 3 until you have selected the echo that you want.
5 Once you have selected the echo that you want, select Confirm Current Echo and press OK.
Recording a waveform
The recorded waveform can be used for comparison purposes, and and can only be reviewed using
FDI tools.
To record the waveform:
1 Select Diagnostics > Waveform > Record Waveform.
2 Press OK. The waveform is recorded in the LWT.
