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.

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 CO2 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.
