General Operation
2.4.1
Display Elements
The Model 6000 uses a character display to depict information about the current state
of the system. The display can be broken down into four basic elements: static fields,
non-editable data fields, editable data fields, and soft key labels.
2.4.1.1
Static Fields
Static fields are elements on the display which do not change from moment to
moment. These can include screen titles and error messages.
2.4.1.2
Non-Editable Data Fields
Non-editable data fields are used mainly to display read back information, such as
temperature, laser current, etc. These fields can have a prefix or suffix label, such as
"Io=" or "mA", and are periodically updated by the system.
2.4.1.3
Editable Data Fields
Editable data fields are used for module and system settings such as current set point,
temperature set point, display contrast, etc. An editable field has three distinct display
states: focused, non-focused, and read-only.
The focused state indicates that the field has the input "focus." When the a field has
the focus, a right pointing arrow (→) is placed to the left of the field. Any keyboard
entry or knob adjustment will be applied to the field, and only one field at a time on
the display can have focus. Move between fields using the up and down arrow keys.
The non-focused state indicates that the field is editable, but does not currently have
the focus. These fields are indicated with a right pointing triangle ( ) to the left of
the field. Using the up and down arrows, focus can be moved to these fields.
When the editable data field is in the read-only state, it looks and acts exactly like a
non-editable data field. Like the non-editable data field, it cannot have focus, and the
up or down arrow keys will skip over the field. This state is used primarily to lockout
specific data elements from front panel change when the Model 6000 is in remote
mode. Any IEEE-488 or RS-232 communication will place the unit in remote mode,
and editable fields that are protected during remote operations change to the read
only state.
2.4.1.3.1
Changing Data Fields
A data field can only be changed from the front panel when the field is the focus.
Some fields are numeric-based, such as current set point or temperature limits. Other
