Data is presented as a gas concentration reading at a specific date and time and may be viewed
collectively as points on a graph (Graph), or individually as a single text record (Single). In Graph view,
readings are presented sequentially in time when scrolling the up and down keys. In Single view, both
the date and time may be scrolled to provide a pseudo random-access method. Since the two views are
connected, it is possible to navigate directly to the date and time of interest using the Single view, and
then switch to the Graph view to see more readings around a particular time. Conversely, the view can
be switched from Graph to Single to view readings taken around the same time on different days.

Samples reported are assumed to be in units of PPM, PPB, or %, as determined by the gas concentration
units appearing on the Main Display. Sample values outside of printing limits are forced to the following
values.
Readings in both views are displayed in the same units and decimal precision as those on the Main
Display, and the date format is consistent
with the format selected in the (see pg 77). Both views also
display special codes to indicate samples were unavailable. The table below summarizes the special
codes.
Dates presented in the Graph view are shortened to just the month and date, the year is not presented.
Turn data logging on or off, or clear stored data.

4. Changing one automatically changes the other two.
Warning: changing the sampling interval will clear the data-log.
