Section 3.2: Model 9100 Controls: Introduction to the Front Panel 3-3
Final Width = 215mm
3.2.2 Front Panel Features
3.2.2.1 Liquid Crystal Display and Screen Keys
The 9100 communicates with the operator by presenting essential information on the LCD screen. For example: the output value
appears in large characters just above the center of the screen, accompanied by its units. An operator can move through a series
of menu screens, choosing options from those presented on the screen.
Eleven soft keys (referred to as 'screen' keys) are grouped below and to the right of the screen. These are labelled by characters or
symbols representing menu choices, which appear in reserved display areas on the screen next to the keys. Main functions are
selected by buttons on the 'Calibration System' panel; some screen keys select sub-functions, others allow different choices to be
made.
3.2.2.2 'CALIBRATION SYSTEM' Panel
This panel carries the main controls used to select the operational functions and modes of the calibrator, and to determine the output
variables:
a. Major Function keys are used mainly in Manual mode (Section 4) and Calibration mode (Section 10). They are arranged
down the right edge:
V: DC or AC Voltage (select DCV or ACV using screen keys).
A: DC or AC Current (select DCI or ACI using screen keys).
Ω: Resistance or Conductance.
Hz: Rectangular Waveform (select Frequency, Mark/Space Ratio, or Duty Cycle using screen keys).
Aux: Auxiliary Functions (select Capacitance, Temperature simulation or Logic Stimulus using screen keys).
b. Mode Key, the bottom key under the Function keys. The modes are: 'Procedure', 'Manual', 'Configuration', 'Calibration'
and 'Test' (refer to sub-section 3.3).
c. OUTPUT OFF and ON keys, with an 'ON' state indicator LED, in a separate column due to their importance.
d. Alpha-numeric keypad, used for various purposes, to be described later.
e. The
(Tab) key, Cursor keys and Spinwheel: These select and increment or decrement numeric quantities displayed
on the LCD screen.
3.2.2.3 Output Terminals
The six safety output terminals and the D-type output socket are located on the left of the panel. Connections to these terminals,
for each of the functions, are described in Section 4.
3.2.2.4 'Procedure' and 'Results' Memory Card Slots
These slots are included mainly for Procedure mode, although there are secondary uses. Procedure mode operations are introduced
in Section 5.
