pressure test (see “(System) Pressure Test” on page 126) determined a problem with the pump.
Tools required p/n Description
8710-0510 Wrench, 1/4 - 5/16 inch, open
Parts required p/n Description
G1312-67500 Calibration capillary assembly
Preparations Place two bottles of HPLC-grade water in channels A and B (A1 and B1 if the pump is equipped with
a solvent selection valve)
The Valve Test should only be performed when firmware revisions < A.06.50 are installed.
For firmware revision A.06.50 or above, perform the Leak Rate Test instead.
Make absolutely sure that the pump is very thoroughly flushed with water before starting
the test! Any trace of other solvents or the smallest air bubble inside the flow path
definitely will cause the test to generate misleading results!
Make sure to release the pressure by opening the purge valve when the test has
completed. Otherwise the pump may generate an overpressure error.
