15.  Check and re-adjust  the internal pres-
sures if required. 
16.  The unit is ready for operation. 
3-3 BINDING 
To achieve full coordination between Analyzer 
Modules and associated I/O Modules, the 
user must bind those components together in 
the System Set Up portion of the Technical 
Configuration Menu in software.  
3-4 CALIBRATION 
Calibration gas setup is as follows: 
1. 
Set oven temperature setpoint. 
2. 
Apply regulated air at a pressure be-
tween 10 and 25 psig. 
3. 
Allow case, oven, and sample tem-
peratures to stabilize. 
4. 
Supply heated zero gas to sample 
inlet. Adjust external flow controller or 
throttle valve so that the sample inlet 
pressure is between 5 and 9 psig., 7 
nominal. 
5. 
Supply heated span gas to sample in-
put. Repeat adjustment described in 
step 3. The reading of the sample 
pressure, oven, and sample tempera-
tures should be the same as that used 
during the adjustment of the zero gas. 
See Section 2-4g on page 2-3 for a descrip-
tion of the method for choosing calibration 
zero and span gases. 
To calibrate the Analyzer Module, introduce 
zero gas into the SAMPLE INLET, and do the 
following: 
1.  If more than one Analyzer Module is 
functional and the split Run Mode dis-
play is shown, press the DISPLAY soft-
key until the desired Analyzer's Run 
Mode display is acquired. 
2.  Press the MENUS softkey to enter the 
Main Menu. 
3.  Verify the fuel type in the Miscellaneous 
Control Parameters menu (under the 
Technical Configuration menu structure, 
select the following from the Main Menu: 
Diagnostic menus, Analyzer Module Di-
agnostics and then Miscellaneous Con-
trol Parameters). 
4.  Verify the capillary type in the Analyzer 
Manufacturing Data menu (under the 
Technical Configuration menu structure, 
select the following from the Main Menu: 
Technical Level Configuration, Service 
Menus, Manufacturing Data, Analyzer 
Module Data). 
5.  In the Calibration Gas List menu (from 
the Main Menu, select Expert Controls 
and Setup, Analyzer Module Setup, then 
Calibration Gas List), enter necessary 
data, including the Operational Sample 
Pressure and the Calibration Gas HC 
Response Factor. Common HC factors 
are: methane (CH
4
), 1.0, ethane (C
2
H
6
), 
1.90, propane (C
3
H
8
), 3.00. These fac-
tors are not used to compensate the 
reading, but are used to select the 
proper preamp sense resistor. 
6.  Press HOME to re-enter the Main Menu, 
enter the Basic Controls menu, select 
desired range, introduce zero gas and 
allow its response to stabilize, press the 
ZERO softkey to enter the Analyzer 
Zero menu, press ZERO again and wait. 
7.  Press the SPAN softkey to enter the 
Analyzer Span menu, introduce span 
gas and allow its response to stabilize, 
press SPAN again and wait. 
8.  Repeat steps 6 and 7. 
9.  Press the HOME softkey to re-enter the 
Main Menu. 
10.  Press DISPLAY softkey for the Run 
Mode display.
