 Attach the outlet port of a flow meter to the sample inlet port on the rear
panel. Ensure that the inlet to the flow meter is at atmospheric pressure.
 The sample flow measured with the external flow meter should be within 
10% of the nominal values shown in Table 10-3.
 Low flows indicate blockage somewhere in the pneumatic pathway.
7.5.4. AC POWER CONFIGURATION
The T-Series digital electronic systems will operate with any of the specified power
regimes. As long as instrument is connected to 100-120 VAC or 220-240 VAC at either
50 or 60 Hz it will turn on and after about 30 seconds show a front panel display.
Internally, the status LEDs located on the Relay PCA, Motherboard and CPU should
turn on as soon as the power is supplied.
On the other hand, some of the analyzer’s non-digital components, such as the pump and
the various AC powered heaters must be properly configured for the type of power being
supplied to the instrument. Figure 7-11 shows the location of the various sets of AC
Configuration jumpers.
