is shown
below.
• Key in the desired inlet pressure according to the
ambient temperature.
• Press Enter.
The four parameters for pump A are now entered.
Entering the Parameters for Other Pumps in
the System
You must tell the 305 Master pump if the slave
pumps B, C, and Inject are present in your system.
By default, pumps B, C, and Inject are set as
present. This can be changed by pressing the
Change soft key when defining the relevant pump.
If a pump is defined as present, the parameters
Refill Time, Compressibility and Head Size must be
defined.
If pump B is defined as absent, the Pump C is
automatically set as absent.
Summary:
• press the Menu soft key.
• press the Pump soft key.
• Select pump (A, B, C or Inj). (Define pumps B, C
or Inj as present or absent.)
• Key in the desired refill time. (Minimum time 125
ms, maximum time 1000 ms.)
• Key in the solvent compressibility. (Minimum
value 0, maximum value 2000 Mbar
-1
.)
• Key in the relevant Pump Head Size. (5, 10, 25,
50, 100, or 200.)
• Key in the Inlet Pressure. (Minimum value 0 MPa,
maximum value 10 MPa.)
When all pumps have been defined, press the Quit
soft key.
