Fundamentals of the instrument dialog

Main menu Each key of the 732 IC Detector opens a main menu

whose thematically arranged submenus can be se-

lected by repeated pressing of this key. The name of the

key always appears in the top line of the display.

Submenu Each submenu has a title which is marked by ">" and

appears in the bottom line of the display. <ENTER> is

used to move from the title to the individual inquiries

where the most important settings of the instrument can

be changed. <QUIT> effects a return to the standby

mode of the instrument.

Inquiries With inquiries without ":" the valves must be entered

using the numeric keys. The inputted value is accepted

with <ENTER> and the next inquiry appears.

In the case of inquiries with ":" the admissible values

must be selected using the <SELECT> key. The set

value is accepted with <ENTER> and the next inquiry

appears.

Depending on the parameter, <CLEAR> is used to

reset the displayed value to the smallest possible value

or the default value. The <CLEAR> key is also used to

abort wrong entries.

<QUIT> is used to quit the inquiries and return to the

title of the submenu.

>PARAM/detector

The title of the submenu "detector" appears that contains

various inquires for the conductivity detector.

ENTER

⇒ Press the <ENTER> key to move to the inquiries.

>PARAM/detector

range: 1.00 mS/cm

The first inquiry shows the measuring range for which 7

stages from 0…100 µS/cm to 0…10 mS/cm are available.

Select the measuring range to ensure that the conductivity

value of the eluent used easily lies within the selected

range.

SELECT

⇒ Press the <SELECT> key until the desired measuring

range appears in the display.

>PARAM/detector

range: 200 µµS/cm

The eluent used for the PRP-X100 Anion Column has a

conductivity of ca. 150 µS/cm. A range of 200 µS/cm is thus

selected as the measuring range.
