3.4. STARTUP, FUNCTIONAL CHECKS, AND INITIAL

CALIBRATION

IMPORTANT IMPACT ON READINGS OR DATA
The analyzer’s cover must be installed to ensure that the
temperatures of the internal components are properly controlled.
If you are unfamiliar with the theory of operation, we recommend that you read
Section 12. For information on navigating the analyzer’s software menus, see the
menu trees described in Appendix A.1.

3.4.1. STARTUP

After the electrical and pneumatic connections are made, turn on the instrument.
The pump and exhaust fan should start immediately. The analyzer should
automatically switch to Sample Mode after completing the boot-up sequence and
start monitoring CO2 and O2 gases.

3.4.2. WARM UP

The T803 requires about 60 minutes warm-up time before reliable measurements
can be taken. During that time, various portions of the instrument’s front panel
will behave as follows. See Figure 3-1 for locations.

concentration
This is normal operation, but deemed inaccurate during the
warm-up period.
Mode N/A Displays blinking
“SAMPLE”
Instrument is in sample mode but is still in the process of
warming up.
Param
(Parameters) N/A
Displays menus,
parameters, and
messages.
Use any warning messages as a means of diagnosing problems.
STATUS LEDS
Sample Green On
Unit is operating in sample mode; front panel display is being
updated.
Cal Yellow Off The instrument’s calibration is not enabled.
Fault Red Blinking
The analyzer is warming up and hence out of specification for a
fault-free reading. various warning messages appear in the
Param field.

3.5. 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
