Start Operator
Pressing this key clears the graph, starts a new graph, sets the time of day
to the present clock time and begins the trending. This key is only available if
trending is stopped. If the selected Chart Type is TRIGGERED and TRIGGER
ACTION is set to START, data collection will not begin until the Triggers have
been satised and any selected TRIGGER DELAY has elapsed. Otherwise, data
collection will begin immediately.
Stop Operator
Pressing this key stops the trending. The trend data is frozen on the display until
another graph is started with the START key. The STOP key is only available if
trending is running.
Print Operator

ISTING, a snapshot of the data presently on the screen is sent to the printer. If
set to NEW, all data collected after pressing this key will be sent to the printer as
it is collected. If set to DISABLED, no data is sent to the printer.
Data Select Operator

single trended data point for display, hiding the other data points. Selections are
ALL DATA or DATA POINT X (1-6).
