Scope Data Screen
NOTE: The scope data feature is intended for use as a diagnostic tool by Livingston. Please contact
Livingston if you need the ability to record scope data.
• Scope Data
This option displays the raw and filtered data from the external sensors. The scope feature must be
enabled in the General Setup in order to view Scope data. For more information, refer to the Scope
Enable and related settings in the General Setup.
Figure 6-33 shows the raw A-D toroid signal (pre-
integration). The left y-axis represents the A-D
counts. The graph heading shows which weld the
waveform is for, as well as how many samples there
were in the waveform. The current sampling rate
used by Livingston monitors in Scope Mode is
about 104 samples per halfcycle.
When the screen is zoomed, as shown in figure 6-
34, the graph heading will read 500 Samples at
Sample # x, where x is the first sample number of a
500 sample series. The graph can be scrolled across
in increments of 100 samples using the Left/Right
Arrows.
Note: The integration algorithm for the current
waveform is not the same as the algorithm used to
calculate current for the main program screen. For
this reason, baseline drift may be observed in DC
waveforms.
