>PARAM/709 IC Pump
Pmax 10.0 MPa
The maximum admissible pressure for the PRP-X100 IC
Anion Column is 34 MPa, the normal operating pressure is
2 mL/min at ca. 7 MPa. A value of 10 MPa is thus entered
as the maximum shutoff pressure.
ENTER
⇒ Confirm the set maximum shutoff pressure with the
key.
>PARAM/709 IC Pump
Pmin 0.0 MPa
The parameter " Pmin " denotes the minimum shutoff
pressure for the 709 IC Pump. If the pressure drops below
this value for a considerable length of time (e.g. owing to
leaks or if the eluent supply is interrupted), the pump is
automatically switched off.
Use the numeric keys to enter here the desired value. This
limit value should be sufficiently far below the normal oper-
ating pressure of the separating column used (1 MPa =
10 bar).
>PARAM/709 IC Pump
Pmin 1.0 MPa
A value of 1 MPa can be entered as the minimum shutoff
pressure for the PRP-X100 IC Anion Column.
ENTER
⇒ Confirm the set minimum shutoff pressure using the
key.
>PARAM/709 IC Pump
flow corr. 1.00
The parameter "flow corr." denotes the correction
factor for the flow of the 709 IC Pump. This correction
factor is used to match the displayed flow to the actual flow.
If you are interested in the exact display of the flow, this
correction factor must be determined by measurement of
the actual flow and then entered here (see section 3.3 of
the 709 Instructions for Use).
ENTER
⇒ Confirm the inputted flow correction with the
key. As this was the last inquiry of the last submenu of the
key, an automatic switch is made to the
standby mode.

The 732 IC Detector is again in the standby mode and the
display shows the status messages.
