6. Turn the instrument on.
7. Make sure the zero air supply to the analyzer’s purge line inlet is supplying gas at a stable
pressure above 7.5 psig.
8. Adjust the GFC 7000TA’s pressure regulator until the attached gauge reads 7.5 psig.
9. Turn off the instrument.
10. Remove the source of zero air attached to the purge line inlet port at the back of the analyzer.
11. Remove the pressure gauge and reattach the end cap removed in step 4 above.
12. Replace the analyzer’s top cover.
3.7. Initial Operation
If you are unfamiliar with the GFC 7000TA theory of operation, we recommend that you read
Section 10. For information on navigating the analyzer’s software menus, see the menu trees described
in Appendix A.
NOTE
The analyzer’s cover must be installed to ensure that the temperatures of the GFC
wheel and absorption cell assemblies are properly controlled.
3.7.1. Startup
After electrical and pneumatic connections are made, and initial functional check is required. Turn on the
instrument. The pump, exhaust fan and PMT cooler fan should start immediately. The display will briefly
show a logo splash screen at the start of initialization.
The analyzer should automatically switch to Sample Mode after completing the boot-up sequence and
start monitoring CO

gas. However, there is an approximately one hour warm-up period before reliable
gas measurements can be taken. During the warm-up period, the front panel display may show
messages in the Parameters field.
