9.4.2. FLOW CALIBRATION
The flow calibration allows the user to adjust the values of the sample flow rates
as they are displayed on the front panel and reported through COM ports to match
the actual flow rate measured at the SAMPLE inlet. This does not change the
hardware measurement of the flow sensors, only the software-calculated values.
To carry out this adjustment, connect an external, sufficiently accurate flow meter
to the sample inlet. Once the flow meter is attached and is measuring actual gas
flow, press:
