IMPORTANT NOTE: Additional diagnostics configuration and scheduling options are available.
Click Help on the Diagnostics screen for additional details.
Figure 6-19 shows the Diagnostics tab as shown from the Startup Wizard. In this example the
analyzer has passed all tests. The following tests are performed:
Carrier Pressure Regulator Test
Oven Temperature Test
Processor Control Test
Stream Test
Figure 6-19: Completed Diagnostics (displayed from the Startup Wizard)
During the diagnostics or upon completion, view the status of the diagnostic tests by clicking
Diagnostics on the Analyzer Operation screen. When the device completes the startup diagnostics
and has passed the appropriate tests (with the exception of streams with no pressure), the device will
go into hold mode. We recommend that the device be allowed to run for at least eight hours to
completely stabilize. Then perform calibration as described in section 7.
6.4.2.1 Carrier pressure regulator tests
This test compares the actual column pressure to the column pressure set point using carrier gas. A
failure of this test indicates that the carrier pressure is not meeting or is exceeding the expected level
of pressure. A failure of this test indicates that the carrier pressure cannot be regulated to the
setpoint.
6.4.2.2 Oven temperature test
This test compares the actual oven temperature to the oven temperature set point. The factory set
point value for oven temperature is 60 C (140 F). A failure of this test indicates that the oven is not
maintaining the required temperature.
