Tutorial Aid
Throughout the tutorials, you will see
pointers (
). Where these are found
in the text, they identify instructions
for you to follow, giving you manual
practice. Arrows (
)are used to
indicate important points on diagrams
etc. (see Fig. 3.4.1 opposite).

Output Controls
The aim of these tutorials is to become familiar with the 9100 interactive display, and the
manipulation of front-panel controls to alter variables, starting with those which affect
output.
In the first tutorials (paras 3.4.4 and 3.4.5), we have chosen DC Voltage as a typical
function for manipulation (it is also likely to be the most familiar to most new operators).
This is not a full treatment of the DC Voltage function — that will appear in Section 4.
The chosen output value is presented just above the center of the display, accompanied
by its units, in large characters.
We have already seen that there are two sets of front-panel controls which manipulate the
output configuration, but briefly, to establish a base-line, here they are again:
1. Controls positioned in the right half of the front panel. They are:
a. Major Function keys, arranged in a column down the right edge:
b. Moving left, the OUTPUT OFF and ON keys, arranged in a separate column
because of their importance.
c. Alpha-numeric Keypad.
d. Cursor Controls:
Cursor keys:
Control the screen cursor to select a digit for adjustment.
Increment or decrement the digit selected by the cursor.
Tab key:
Moves the cursor around the screen, between relevant
variables (in our early sessions with DC Voltage, we shall
have no reason to use this key).
Spinwheel:
Increments or decrements the selected digit.
2. Screen Keys around the display itself, which are used to select sub-functions
(identified in the areas used as screen key labels);
Before we proceed, we need to identify the components present on a typical menu screen.
A representation of a DC Voltage display appears opposite.
Entry to Manual Mode
The tutorials are conducted in Manual mode, which you may not recognize at present.
Refer to paras 3.3.1.1 on page 3-5. To enter MANUAL mode:
Press the front panel Mode key;
Press the MANUAL screen key beneath the display.
