LPM, 3 LPM, and 5 LPM), and compare the "internal" value (from the instrument's flow
sensors) with the "external" value measured by the external flow meter.
12. Note the flow on your external mass flow meter.
IMPORTANT! - make sure that your flow readings are reported at the same reporting
conditions of T and P as the instrument's setting.
13. Press the empty box marked 'Flow' and enter the flow from the external flow meter.
IMPORTANT ! – units are milliliters per minute (mLPM).
14. Confirm by pressing "OK". The process will repeat at the three flow values.
15. After entering the last value (@ 5LPM) and pressing "OK", the instrument will show the
flow verification report. This report is also saved on the CF card and is available for download
with data files.
