12. Allow the analyzer to warm up then perform a leak check on the
sample system fittings that were disconnected. See “Sample System
Leak Check” in Chapter 3.
Analyzers without Heated Cells:
If the leak check passes, continue with Step 13.
Analyzers with Heated Cells:
If the leak check passes, replace the Insulating Jacket or close the Oven
door to allow the Cell to warm up to normal operating temperature
and stabilize and then continue with Step 13.
13. Perform an Auto-Setup.
14. After the Auto-Setup is complete, change the Flow Control setting to
‘2’ (zero) and perform a manual Zero. Click OK then Apply. Do not
save the changes to EEPROM.
15. After the Zero is complete, change the Flow Control setting to ‘0’
(auto). Click OK then Apply (next to Flow Control). Click OK then
save this parameter change to EEPROM by clicking the Save CFG to
EEPROM button on the Setup tab.
16. If the analyzer uses measured Pressure Compensations (optional),
return the setting to measured.
17. Open the valves isolating the analyzer from the sample stream and/or
remove the cap from the Vent Line outlet.
18. Close the Configurator Software, power down the computer, and
disconnect the serial cable from the analyzer’s Communications Port.
Close the Communications Port cover and hand-tighten the screw to
secure it in place.
19. Using a soft, nonabrasive cloth, gently clean the joining areas (flame-
path) of the Upper Enclosure and its door and replace the (24) M10
screws. Tighten the M10 screws to 9.0 Nm, ±1.0 Nm (80 in.-lb, ±9
in.-lb).
The procedure is complete.
