4.14 Viewing the Trend Graph
The Trend graph is drawn using one minute average readings so it is not suited to viewing short-term signal
fluctuations.
To view the graph:
24) Touch the Menu Icon>Information>Trend/Plot.
25) Touch the required channel, and then touch [Select].
26) Select the required Data Range (1/2/4/8 hours) and then touch Plot. (Alarm Threshold is shown by
default.)
27) The trend graph will be displayed. Use the arrows to move backwards or forwards in time; use the X or
[Cancel] to exit.
Note: The TPPLW Trend / Plot will retain up to the latest 8 hours of data but will be cleared after a power
reset.
Note: TPPLW does not adjust automatically for daylight savings time but it will retain a backup of the earlier
data if the system clock is backdated (e.g. when ending daylight savings time).
