6.9.8. 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 (see Chapter 11 for more details). Once the flow meter is attached and is measuring actual
gas flow, press:
