Trend Chart - Data Log Mode
This topic applies only to the 34465A/70 DMMs, data logging is standard for these DMMs. See Data Log-
ging for more information on how to configure data logging.
When the DMM is in data log mode, Zoom, Pan, and Cursor trend chart controls are available. To enter
data log mode, press [Acquire] > Acquire softkey > Data Log .
To select the trend chart, press [Display] followed by the Display softkey:
In the data log mode, trend chart behavior depends on whether you are data logging to instrument
memory, or data logging to a file(s).
Data Logging to Memory
When data logging to memory, the trend chart maps each reading to a dot in a pixel column, draws a line
between multiple dots in each column, and draws a line from the last reading in a column to the first read-
ing in the next column.
When data logging to memory, Zoom, Pan, and Cursors are available and operate as described above in
the digitize section.
Data Logging to File(s)
When data logging to files, the trend chart behaves in a manner similar to that of the continuous meas-
urement mode. That is, the number of readings shown per pixel column depends on the reading rate and
the selected Time Window.
