2.8.3 TIME BASE
The [Time Base] option list defines the stripchart x-axis display interval. The stripchart
plots an average of readings obtained during the elapsed time between reports. Stripchart
resolution is 1 data point per pixel, of which there are approximately 100 on the short stripchart
plot and approximately 200 on the full screen stripchart plot. Five pixel reports occur be-
tween major stripchart divisions.
NOTE: The stripchart display identifies the “real time” when the computer records
the most recent graduation. You can time-stamp any graduation by counting
back in graduation intervals. The default interval setting is 1 second.
