Right Triangle Functions:
R Length of Unknown Side — Calculates Side “x” of
unknown Right Triangle.
r Length of Unknown Side — Enters Side “y” of
unknown Right Triangle.
d Hypotenuse — Enters “c” of Measured Triangle as
“r” of unknown Right Triangle, for final determination
of “x” and “y.”
p Theta — Finds unknown angle for determination of
“x” and “y.”
OFFSET KEYS
Ç ( Offset — Calculates offset measurements, including
the Centerline Radius, Wrapper Length/Stretch-out,
Heel Radius, Throat Radius and Theta, given entry
of “x” (actual length), “y” (offset), and “a” (“end a”)
into the keys below:
Press Result
1 Centerline Radius (CR)
2 Wrapper Length/Stretch-out (WL)
3 Heel Radius
4 Throat Radius
5 Theta (THET)
6 Redisplays entered “x” (Actual Length)
7 Redisplays entered “y” (Offset)
8 Redisplays entered “a” (Storage
Register “a” or End “a”)
R Actual Length — Enters the actual length “x” for
offset calculations.
r Offset Length — Enters the offset “y.”
Ç 4 Storage Register “a” — Enters length of “end a”
for offset calculations.
