Overview of the Module’s Indicators and Test Functions
System Pressure Test
The System Pressure Test is a quick test designed to determine the pressure
tightness of the system (i.e. the high pressure flow path between pump and
column). After exchanging flow path components (e.g. pump seals or injection
seal), use this test to verify the system is pressure tight, see “System Pressure
Te s t ” on page 97.
Leak Rate Test
The Leak Rate Test is a diagnostic test designed to determine the pressure
tightness of the pump components. When a problem with the pump is
suspected, use this test to help troubleshoot the pump and its pumping
performance, see “Leak Rate Test” on page 102.
