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 description 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 (CH4), 1.0, ethane (C2H6), 1.90, propane (C3H8), 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.
