Using the Graph
The graph on the main screen consists of a strip-chart. When the software is in Run or Record mode, the strip-chart
scrolls from right to left at a rate of 1 group of plots per second. The complete graph displays the last 60 plots (or 60
seconds) of data. Previous data points that scroll off the graph are saved in memory and can be viewed at any time until
the graph is cleared or the application is closed.
Viewing Graph History
If the strip-chart contains more than 60 points of data, select the
View History
checkbox located on top of the upper
left hand corner of the graph. A horizontal scroll bar will appear below the graph allowing the operator to scroll
through the data. The current incoming data will not be lost while viewing history data, so it can be done while the
Hydraulic Analyzer is in Run or Record mode. When
fi
nished viewing the history data, un-check the
View History
checkbox and the graph will return to displaying the current real-time data.
Displaying and Hiding Individual Graph Plots
The top of the graph contains a color coded legend for each plot. Next to each legend label is a checkbox that
controls the visibility. A “checked” box displays the plot and a “un-checked” box hides the plot.
Adjusting the Graph Scales
The scale of each plot (Pressure, Temperature, and Flow Rate) can be independently adjusted so the plot is
displayed over most of the graph height. The pressure scale is located on the left hand side of the graph while the
temperature and
fl
ow rate scales are located on the right hand side. Under each scale is a left and right arrow used
for scale adjustment. The left arrow decreases the scale and the right arrow increases the scale. Scale adjustments
can be made while in Run or Record modes.
Displaying Graph Gridlines
The horizontal graph gridlines can be displayed by selecting
View – Show Graph Gridlines
.
Clearing the Graph
Press the
Clear Graph
button or select
View – Clear Graph
from the menu.
Using the Alarms
There are three sets of High / Low alarm indicators on the main screen which monitor pressure, temperature, and
fl
ow rates. The alarm indicators
fl
ash if the current system measurements exceed the alarm limits set by the operator.
The alarms continue to
fl
ash when the current system measurements return back to normal to alert the operator that
an alarm condition occurred. The operator must reset the alarms manually to acknowledge the alarm condition. Upon
exiting Run or Record mode, the operator can view all alarm events (time, value, alarm level) in another form. These
alarm events are also recorded to the .csv
fi
le when in Record mode.
