Flow Rate Calibration
To calibrate the flow rate on the F-900, a separate flow meter is required. Please contact Felix
Instruments Support for detail instructions.
Setup Time and Date
To change the time and date on the F-900, press the right arrow
when “Time” is highlighted on
the Setup Menu. This utility allows the user to set-up the instrument in different time zones or to
adjust the time after daylight savings.
To change the time on the instrument, use the up/down arrows to change the values.
Use the left/right arrow to highlight the appropriate column. Then, make the appropriate
shift in time and press Save.
Setup Flow
The air flow of the F-900 is an important factor for taking good measurements. The default flow
rate is 80 ml/min. Flow rate is adjustable from 80-200 ml/min.
A flow value below 80 ml/min can negatively impact sensor functionality. If measuring bottled
gas, a lower flow rate may be used in order to reduce gas waste. If measuring open air, a higher
flow rate (~200 ml/min) is acceptable.
The default flow rate is 80 ml/min
.
To make adjustments:
1.
Go to Setup>Flow and press the right arrow.
2.
Use the up/down arrows to adjust the value.
3.
The Set Flow value is found in ml/min to the far right.
4.
The Actual Flow value will change to match the set flow.
5.
Press Save to save changes and exit back to the Setup Menu.
6.
Press Stop to exit back to the Setup Menu without saving.
