The analyzer’s cover must be installed to ensure that the temperatures of
the GFC Wheel and absorption cell assemblies are properly controlled.
If you are unfamiliar with the T300/T300M theory of operation, we recommend that you
read Section 13. For information on navigating the analyzer’s software menus, see the
menu trees described in Appendix A.
3.4.1. STARTUP
After the electrical and pneumatic connections are made, an initial functional check is in
order. Turn on the instrument. The pump and exhaust fan should start immediately. The
display will briefly show a momentary splash screen of the Teledyne API logo and other
information during the initialization process while the CPU loads the operating system,
the firmware and the configuration data 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.
3.4.2. WARNING MESSAGES
Because internal temperatures and other conditions may be outside the specified limits
during the analyzer’s warm-up period, the software will suppress most warning
conditions for 30 minutes after power up. If warning messages persist after the 60
minutes warm-up period is over, investigate their cause using the troubleshooting
guidelines in Section 12.
To view and clear warning messages, press:
Suppresses the
warning messages.
Press CLR to clear the current
message.
If more than one warning is
active, the next message will take
its place until all are cleared.
Once the last warning
has been cleared, the
RANGE function will
be displayed.
NOTE:
If a warning message persists after
several attempts to clear it, the message
may indicate a real problem and not an
artifact of the warm-up period.
