“Display clear” (clear display) touch switch
Clears the trend graph display. The logging data is not cleared but re-
tained.
“Log clear” (clear log) touch switch
Clears all the logging data. At the same time, the trend graph being dis-
played is also cleared. This switch clears only the trend graph being dis-
played. The trend graph plotted on other screens are not cleared. This
switch is valid only when the data logging function is used. This touch
switch is only effective when using the data logging function.
“Previous page” (rewind) touch switch
Displays logging data older than that of the currently displayed trend
graph. This touch switch is only effective when using the data logging
function.
With a standard type trendgraph, if this touch switch is pressed during
display of the latest data to backtrack to past data, and then the “next
page” (forward) touch switch is pressed to return to display of the latest
data, the latest data is plotted following the past data.
Example:
“Next page” (forward) touch switch
Displays logging data newer than that of the currently displayed trend
graph. This touch switch is only effective when using the data logging
function.
When the latest data is displayed during data logging, updating of the
trend graph display is automatically restarted.
The “previous page” (rewind) or “next page” (forward) touch switch, whichever
was pressed last, remains lit.
