Figure 42 Graphical Display with Data Logger
If the data logger module is installed, you can move quickly on the time
axis: zoom out, move the cursor, and zoom back in.
The time that is shown below the graph is adjusted with the current time
offset of the transmitter. If you change the transmitter's date and time
setting, the displayed timestamps in the history graph change
accordingly. For an explanation of the effect of changing the date and
time manually, see section Data Logger Module on page 60.

A question mark after time tells you that at least one power failure
(dashed vertical line) has occurred after the chosen moment. In this case,
the actual time difference between the present and the cursor position is
not exactly known. If the data logger module is installed, the time is
known and the question marks are not present.
