5.1 Test Configuration

5.1.1 Test Configuration Menu
The Test Configuration Menu allows you to:
❑
Program and activate process setpoints (leak rate pressure and audio)
❑
Enable or disable leak detector advanced features
❑
Select Leak Detection specific applications with auto parameters setup with step-by
-step instructions for enhanced operation.
5.1.1.1 Reject and Audio Set Points
Reject and Audio Set Points make the acceptance and rejection of parts more obvious. By
creating a set point, you let the system indicate if the part meets specification or not. For
example, you select LEAK RATE #1, set the value to 1.0E-8, set the reject activation to
greater than > (activate when the leak rate is above that set point), and turn the set point
ON. Then when the system is put into TEST, it indicates on the front panel that the part has
not meet the set point requirement, until it gets below the set point value and then the set
point failure indication disappears.
Multiple set points are used when you want to indicate several levels of acceptance. There
are times when you may want to assure the leak detector is working properly by bounding
the failure limit. For example, if LEAK RATE #1 were set as per above, then any leak rate
below 1.0E-8 would pass the part. Also assume that the leak detector was not seeing
helium, it would always pass parts. One way of preventing this from happening is to
periodically read the internal calibrated leak. Another way is to place a 5.0E-10 range leak
into the test port along with the part and program a second reject set point to fail if the leak
detector were to go below that value. In that case, you would program LEAK RATE #2 to
4.7E-10, set the reject activation to less than < (activate when the leak rate is below that set
point), and turn the set point ON. In this case, when the system is put into TEST, the system
indicates a failure if the leak rate goes below 5.0E-10.
