There are various alternative views that may be selected using the 

NEXT 

and

 LAST 

buttons in 

the lower status window, these are as follows: 
 

DEFAULT DISPLAY 

 

The default display shows when the instrument is first powered on. It shows a 
customizable graphics area that can be programmed by the user through a USB 
memory stick to show up to 300 individual colour images (1 for each test available). 
This could be used to present operators with graphical/textual guides on any manual 
interaction needed within various stages of a product under test. 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

GRAPH DISPLAY 

 

Shows a graph plotting the various stages of a test in real time whilst the test is 
running. Pressure readings are plotted in blue with their scaling shown against the left 
vertical axis. Leak readings are plotted in red with their scaling shown against the 
right vertical axis. The horizontal axis is pre-scaled to show the length of the full test 
in seconds with vertical sub-division lines and times to mark each stage of the test. 

 
 
 
 
 
 
 
 
 
 

 
 
 
 
 

 
 
 

 

The graph plot will automatically clear when a test cycle ends and its axis will 
automatically scale itself when a test starts. 

Customizable user 
graphic showing 
for test 1. 

Dashed test stage division 
lines indicate when a new 
test stage starts 

Axis are automatically 
scaled when a new test 
Starts.
