through 6. The Y-Axis minimum and maximum values
for each parameter are entered as Data Point Min and
Data Point Max for Data Points 1 through 6. The inter-
val at which all the parameters are sampled is selected
as the Data Collection Interval.

PROGRAMMABLE
Chart Type
Access Level Required: OPERATOR
Selects Continuous, One Screen Or Triggered type of
graph.
Collection Interval
Access Level Required: OPERATOR
Selects the interval at which the parameters are sam-
pled. There are 450 data points displayed across the
X-Axis of the graph. Each point represents the instan-
taneous value of the parameter. The user selects the
time interval between these points. This is called the
Data Collection Interval, or the interval at which the
parameter is sampled. This interval is programmable
over the range of 1 second to 3600 seconds (1 hour), in
one second increments. The selected interval not only
determines the sample interval, but also the full screen
time display. The full screen time display is a result
of the selected interval in seconds, multiplied by the
450 data points. For example, if the Data Collection
Interval is programmed for 900 seconds, the param-
eter would be sampled every 900 seconds, with the last
112.5 hours (4.7 days) of data viewable on the screen.
