c. A flow meter can be used in conjunction with the T-valve to be sure that the flow
going into the F-900 is at appropriate levels and gas is not being wasted.
Connect your standard gas to the input of the flow meter and adjust your
regulator to the proper flow rate. Then connect from the output of the flow meter
to the ‘in’ port of the unit.

Standard Operating Procedure
A similar menu flow is set up for each sensor on the F-900. Deviations from these standard
operations will be further addressed under the specific sensor below. The F-900 will
automatically close and open the needed valves for offset and span calibrations without manual
change being required by the user.
1. Under the Setup>Calibration menu choose the sensor you wish to calibrate by pressing
the right arrow when desired sensor is highlighted.
2. Options for calibration parameters and recalibration can be seen. Select Re-Calibration.
Note:
Changes to any of the calibration parameters should be performed under
the supervision of a Felix Instruments technician only
3. The display will prompt you to attach the appropriate standard gas for setting your
internal offset.
4.
Connect your standard gas for the offset to the ‘in’ port on the front of the unit and press
‘enter’.
5. The instrument will automatically begin to set the offset and will give a countdown to
completion.
6. Once the offset is set the display
will automatically change to ‘set parameter’.

The ‘set parameter’ display will prompt you to enter the exact concentration of your
standard gas. This can be found on the spec sheet delivered with your standard gas
tank.
