Simple Histogram
Try the example:
Open LabVIEW
Select the RGA LabVIEW Library
Open the Simple Histogram example, SRSRGAa Simple Histogram
From the front panel of the VI, set the COM port that the RGA is using
Set the noise floor, mass, and electron multiplier state
Run the VI
The VI takes a few moments before the scan begins in order to perform some initialization tasks on the
RGA. After this time, you should see histogram bars corresponding to the partial pressures detected by
the RGA as its mass filter is swept. If the trace does not appear after thirty seconds or you get an error,
use the RGA COM program supplied with your RGA to verify communications are set up correctly.
Make sure the power to the RGA is on (check the power LED), verify the COM port setting is correct,
and test the cabling.
