7.5 Setup
Certain settings of the pH/Ion Meter can be found in the
Setup
menu.
This menu cannot be accessed from the normal instrument display, as
alterations to these settings have a great influence on the functions of
the pH/Ion Meter.
The
Setup
menu is called up immediately after the instrument has been
switched on by pressing down and holding down the
<CONFIG>
key.

Be very careful when making alterations in this menu! Alterations have
a very large influence on the functions of the instrument. Accidental
alterations can be rejected by carrying out a deliberate memory initial-
ization (see Section 8.5).

You can disable certain keys and functions, e.g. to prevent unwanted
alterations to the instrument settings or method parameters.
You can activate such a disablement by setting the corresponding pa-
rameter to '
ON'. This does not affect access to the Setup menu in any
way.
Please note that configuration settings (i.e. CONFIG/report/id1 and
id2) and parameters (i.e. manual calibration concentrations or stand-
ard additions), which are edited during a measurement or calibration
procedure, are modified that way even if
<CONFIG>
or
<PARAM>
are locked. The advantage is that the requested settings and parame-
ters only have to be confirmed during repeated procedures.
Please note that all disablements will be invalidated if a RAM-Init is car-
ried out (see Section 8.5).
