To manually position latency or amplitude markers, select the marker from the Cursor Panel below the
waveform screen. From that panel, you can Clear, Clear All, Hide, Show, Fast Mark or place individual marker.
To remove a marker, click the undesired marker on the waveform, it turns red. Then select Clear from the
Cursor Panel
5.
To repeat on additional traces, use the Up/down Cursor keys to activate the correct trace and repeat the
previous steps.
Resetting the markers
If you have repositioned markers that have been placed automatically by the system, you can return those markers to their
original positions by pressing Results > Reanalyze in the menu bar.
Erasing data
1.
Click the waveform to highlight it.
2.
Right-click the waveform.
3.
Select
Erase
. Data is removed from the trace and results are cleared from the Results Table.
4.
To undo the erase, right-click the waveform and select
Unerase
.
IMPORTANT: If unerasing data, it needs to be done immediately.
Deleting data
1.
Click the waveform to highlight it.
2.
Click the
Delete
function key.
3.
The data, trace and site are deleted from the trace area and Results Table.
IMPORTANT: There is no undo once data has been deleted.
Superimposing traces
1.
Click the
Superimpose
function key. All waveforms for a given channel are superimposed.
The superimposed traces are displayed in the center of the screen.
2.
Click the
Superimpose
function key again to return the traces to their original positions.
Calculate the velocity
•
Distances may be entered after each site has been acquired, or all distances may be entered after all sites have been
acquired.
•
Enter distances in
cm
to one decimal place (e.g., 23.5cm / 235mm)
•
The distance entered will be displayed in the Results Table in the corresponding Distance field.
•
Press
Enter
to accept the distance and to calculate the conduction velocity.
NOTE:
Enter Default Distances using the protocol table. Conduction Velocities will be calculated automatically.
