4.13.7.5. 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:
Adjust these values
until the displayed
flow rate equals the
flow rate being
measured by the
independent flow
meter.
