7.3 Setup
Certain settings of the pH meter can be found in the setup menu. This
menu cannot be accessed from the normal instrument display, as alte-
rations to these settings have a great influence on the functions of the
pH meter.
The setup menu is called up by pressing down and holding down the
<CAL> key while switching on the pH meter.

Attention!
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 RAM initializa-
tion (see Section 8.3).

With all funct. you can disable all functions as well as the <CAL>
key, e. g. to prevent unwanted alterations to the instrument settings.
The measuring mode can be changed nevertheless. The <CAL> key
can be locked separately.
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 all disablements will be invalidated if a RAM-Init is car-
ried out (see Section 8.3).
