8.4.3.5 Preliminary Steps. Once the DFG SETUP switch is turned
on, select the proper setting on the rotary switches at the rear of the drawer.
The "10 SEG/20 SEG/INV" switch should be in the "10 SEG" posi.'t"ion, which sep-
arates the unit into two independent 10-segment DFG's. The switch marked
''MULT'' determines the maximum slope change per segment; rules for determining
the best setting are covered in Paragraph 8.4.4. For the function such as
the one in Figure 8.2, a setting of "lll is adequate.

4.3.6 Slope Switches. Turn all slope switches off for the
. . , DFG being set up.
8.4.3.7 Setting x and f(x). Now set up the values of x and
f(x), starting from x
=
0 and proceeding out from the origin toward the
maxim1m x. The breakpoint value is read directly on the DVM; to read the
corresponding function 'Talue, depress the appropriate switch. Each switch
is momentary; it must be held down while setting f(x). When the switch is
released, the breakpoint
~e
x is again displayed.
Table 8.2 gives detailed information on which switch to depress at any given
time. The table applies to any ten"!'segment function with positive inputs;
the values of x and f(x) have been left blank, except for the initial and
final values of x, which must be zero and one.
