k Initializing and Standardizing the V-Window
u To initialize the V-Window
1. From the Main Menu, enter the GRAPH mode.
2. Press !3(V-WIN).
This displays the V-Window setting screen.
3. Press 1(INIT) to initialize the V-Window.
Xmin = –6.3,
Xmax = 6.3,
Xscale = 1,
Xdot = 0.1
Ymin = –3.1,
Ymax = 3.1,
Yscale = 1

θ max = 2π (rad), Tθ ptch = 2π /100 (rad)
u To initialize the V-Window in accordance with an angle unit
In step 3 of the procedure under “To initialize the V-Window” above, press 2(TRIG) to
initialize the V-Window in accordance with an angle unit.
Xmin = – 3

Xscale =
π /2 (rad),
Xdot =
π /21 (rad),
Ymin = –1.6,
Ymax = 1.6,
Yscale = 0.5
u To standardize the V-Window
The following are the standard V-Window settings of this calculator.
Xmin = –10,
Xmax = 10,
Xscale = 1,
Xdot = 0.15873015
Ymin = –10,
Ymax = 10,
Yscale = 1

θ min = 0,
T
θ max = 2π (rad), Tθ ptch = 2π /100 (rad)
In step 3 of the procedure under “To initialize the V-Window” above, press 3(STD) to
standardize V-Window settings in accordance with the above.
