This page is divided up into 2 parts: the graph display area with black background is the main page and the left is
the graph display setup area.
“
Curve
”
check box: Placing a check mark to the left of the graph name displays the corresponding graph in the
graph area. Clicking the color box to the right of the graph name changes the color of the graph. You can change
the text color of the coordinate by clicking the color box to the right of
“
Text Color
”
, or change the coordinate
grid color by clicking
“
Grid Color
”
color box.
“
Coordinate
”
check box: Select to display the graph at different magnifications. Magnification can be changed in
the range of 10-4~108 (default is 100). Once it is changed, the curve displayed on the vertical ordinate will be
changed accordingly.
“
Time
”
: Used to change range of the time scale. 1mul stands for 50 sec per scale, 2mul for
25 sec, 5mul for 10 sec and 10mul for 5sec. Once it is changed, the curve displayed on the horizontal ordinate will
be changed accordingly.
“
Reset
”
button: Press to restore the colors of the curves into defaults.
“

button: Press to print the graph.
At the bottom of the page, the
“

Data Analysis and Printing
The data analysis page is used to perform statistical analysis on collected Flowmeter data. Its contents include:
Qmax: Maximum values of flow rate and flow velocity;
Qmin: Minimum values of flow rate and flow velocity;
Qavg: Average values of flow rate and flow velocity;
Dev: Deviation of flow rate and flow velocity;
UPmax: Maximum upwards variable rate of flow rate and flow velocity;
DPmax: Maximum downwards variable rate of flow rate and flow velocity;
