If you were doing a leak test, you would change the value in the box labeled ““Leak Ref”” to a reference
value. This is the value you wish to classify as a leak. If the partial pressure of the mass selected for leak
testing approaches this value, a tone is generated. The tone goes up in pitch the closer the partial pressure
is to the reference value.
If you wish to change to a linear scale, click the button labeled ““Log””. This toggle switch goes back and

Using LabVIEW 6i to Broadcast RGA Data
Reminder: SRS does not support LabVIEW. What follows is simply provided as a guide
that should help you put your SRS RGA data on the web. You may need to make other
changes to your computer, LabVIEW, or network environments. Contact National
Instruments (
