7.4.6.3 Pump Capacity Test Log

Figure 43: Pump Capacity Test Log Menu

The pump capacity test is used to determine the condition of the aspirator or vacuum pump

which in turn will have a direct impact the flow of gas through the analyzer. A reduction in

pump capacity can result in a reduction in gas flow and as a result on the stability of the

analyzer reading. See page Error! Bookmark not defined. for additional information on

the pump capacity test. As the last step of the test, the system automatically puts an entry in

the pump capacity test log for future reference. See Figure 43. Review of this information

can be useful in detecting a trend in the condition of the aspirator or pump which can result

in a need to rebuild the pump.
