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 strip-chart plot and approximately 200 on the

full screen stripchart plot. Five pixel reports occur between 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.
