7.5.5.3 Pump Capacity Test Log
The pump capacity test can be used to determine the ultimate vacuum that the aspirator or
pump is capable of pulling. Proper flow through the analyzer is a direct result of the proper
balance between the pressure on the analyzer inlet and the vacuum at the analyzer outlet. If
either is incorrect, the flow will suffer and the moisture readings will not accurately reflect
the condition of the process gas. See page 70 for additional information on the pump test.
As the last step of the test, the system automatically puts an entry in the pump capacity test
log for future reference. See Review of this information can be useful in detecting a trend
in the pump condition which can result in a need to rebuild the pump.
