Settings on the Data Log Setup page select one of the 12 discrete sampling intervals listed in Table 17,
and control starting, stopping and clearing of the data-log.

Data Log View Menu
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 %LEL 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 page 79). 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.
