Ethylene Sensors
Ethylene PPB Sensor
Setting the offset for the ethylene ppb sensor deviates from the SOP given above and the
procedure is described below.
1. Select the re-calibration function for the ppb C2H4 sensor.
2. The display will ask you if you want to use the KMnO4 chamber as zero source, press
‘enter’ for yes.
Note:
It is advisable to use this option. If zeroing the PPB C2H4 sensor with a
standard gas rather than using the KMnO4, an additional step of setting up zero
gas is required (with the exact amount of C2H4 in gas source). Contact Felix
Instrument Support if you need further instructions for this routine.
3.
After pressing ‘enter’ the display will immediately prompt you to ‘connect calibration gas’,
this is referring to your standard gas for setting span.
4.
The next screen will ask you to ‘set parameter’ where you enter the exact concentration
of your standard gas.
Press ‘save’.
Note:
The entered concentration should be in ppb. If your standard gas spec
sheet reports the value in ppm, convert to ppb.
5. The F-900 will automatically start setting offset using the KMnO4 in Chamber out and
will give a countdown to completion. Zero calibration takes the instrument around 15-20
minutes to complete.
6. Once offset has been set, the F-900 will immediately start setting span with your
calibration gas.
7. The final display
will show ‘calibration results’ and prompt the user to accept by pressing
‘enter’ or pressing ‘stop’ to cancel the calibration.
Ethylene PPM Sensor
The ethylene PPM sensor re-calibration deviates slightly from the above SOP of calibration.
Please see the steps below for proper calibration. This calibration requires KMnO4 be placed in
Chamber Out. Ensure that this is the case before beginning calibration.
1.
The starting screen will give the prompt to ‘set parameter’. Here you will enter the
concentration of the standard gas to be used for the span calibration in ppm and press
‘save’.
2. Display will prompt to connect the standard gas specified.
3. The calibr
ation will automatically proceed from here with ‘Setting Offset’. The setting
offset portion of this calibration assumes that KMnO4 is in Chamber Out.
4. The calibration will automatically proceed to the span calibration using the previous
specified standard gas.
5.
The final display will show ‘calibration results’.
CO2 Sensors
The CO
2
sensor needs to be enabled in the Setup>Sensor>Sensor Selection menu to access
the Setup>Calibration>CO
2
menu.
