When troubleshooting flow problems, it is a good idea to first confirm that the
actual flow and not the analyzer's flow sensor and software are in error, or the
flow meter is in error. Use an independent flow meter to perform a flow check as
described in Section 10.3.4. If this test shows the flow to be correct, check the
pressure sensors as described in Section 11.6.8.
