Subfunctions: Once a Function is entered, the UP/DOWN switch
is used to select between any subfunctions displayed on the VFD screen.
Parameter values: When modifiable values are displayed on the
VFD, the UP/DOWN switch can be used to increment or decrement the
values.
1.5.2 ESCAPE/ENTER Switch
Data Entry: The ESCAPE/ENTER switch is a 3-way switch used
to input data, from the alphanumeric VFD screen into the instrument:
•
Escape Moves VFD display back to the previous screen in
a series. If none remains, returns to the
Analyze
screen.
With subfunction selected, moves VFD back
through items on screen, to first item, then moves
VFD to previous display.
•
Enter With a Subfunction Selected: Moves VFD on to the
next screen in a series. If none remains, returns to
the
Analyze
screen.
With a Value Selected: Enters the value into the
analyzer as data. Advances VFD to next operation.
(See Chapter 4 for details.)
1.5.3 Displays
Digital Meter Display: The meter display is a LED device that
produces large, bright, 7-segment numbers that are legible in any
lighting. It produces a continuous readout from 0-100%. It is accurate
across all analysis ranges without the discontinuity inherent in analog
range switching.
