Access codes
All instrument access codes are fixed, i.e.
they cannot be modified. When the instrument
requests the access codes, it recognises the
difference between codes (cf. Fig. 5.3):
•
CAL key + Code 22:
Access to Calibration
and Offset menus.
•
ENTER key + Code 22:
Access to the
Configuration menus, allowing
configuration and user-specific settings.
•
PLUS/ENTER keys + Code 9999:
Locks
the keypad.
•
CAL/MINUS keys + Code 0:
Unlocks the
keypad.
•
CAL or ENTER key + any Code
: Access
to Read mode, i.e. all settings can be read
but not changed.

Menu structure
The configuration and calibration functions
are arranged in a menu structure by function
groups.
The function groups are selected in the setup
mode with the PLUS and MINUS keys.
The ENTER key is used to move from one
function to the next within a function group.
The PLUS and MINUS keys are used for
option selection and editing. Selections must
be confirmed by pressing the ENTER key.
This also moves the cursor to the next
function.
Pressing the PLUS and MINUS keys at the
same time terminates programming (return to
main menu).
Note:
•
If a change is made but not
confirmed by pressing the ENTER
key, the previous setting is
retained.
•
See the appendix of these
operating instructions for an
overview of the Liquisys M
menu structure.
