1.27 How to operate the menus

The instrument has two menus accessible to the user :
'Configuration menu' (key SQ) (<)
'Fast access' menu (key UP) (5)
Configuration menu
The 'configuration menu' modifies the configuration parameters
to adapt the instrument to the application needs. To access the
'configuration menu' press for 1 second the SQ (<) key. This access
can be blocked by activating the 'Password' ('PASS') function.
While operating the 'configuration menu', the alarm status is 'hold'
to the status they had before accessing the menu, and the output
and control modules remain in 'error' state. When leaving the
'configuration menu', the instrument applies a system reset, followed
by a brief disconnection of the alarms and the output and control
modules. Functionality is then recovered.
For a detailed explanation on the 'configuration menu' see section
1.29, and for a full view of the 'configuration menu' structure see
section 1.29.
'Fast access' menu
The 'fast access' menu is an operator configurable menu, providing
fast and direct access to the most usual functions of the instrument
with a single key pad stroke. Press key UP (5) to access this menu.
See section 1.19 for a list of functions eligible for 'fast access' in
this instrument. The 'Password' ('PASS') function does not block
access to this menu. Accessing and modifying parameters in the
'fast access' menu does not interfere with the normal functionality
of the instrument, and it does not generate any system reset when
validating the changes.
Front key pad description
Key SQ (<) - press the SQ (<) key for 1 second to access the
'configuration menu'. Inside the menu, the SQ (<) key functions
as a 'ENTER' key. It selects and accesses the menu option currently
displayed. At menus with numerical value entries, it validates the
number displayed.
Key UP (5) - the UP (5) key gives access to the 'fast access' menu.
Inside the menus, it moves vertically through the different menu
options. At menus with numerical value entries, it modifies the digit
selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Key LE (3) - inside the menus, the LE (3) key functions as the
'ESCAPE' key. It leaves the selected menu, and eventually, will leave
the whole menu. When leaving the 'configuration menu' with the
LE (3) key, the changed parameters are activated. At menus with
numerical value entries, the LE (3) key allows to select the active
digit. To modify the value of the selected digit use the UP (5) key.
Menu 'rollback'
After 30 seconds without interaction from the operator, the
instrument will rollback and leave the 'configuration menu' or the
'fast access' menu. All changes will be discarded.
