Use
the rugged Trig Plus III in the office or out in the field to build
precisely and improve your bottom line! Perform advanced trigonometry,
measurement and design problems with ease and accuracy.
- Dimensional Math & Conversions
Works in all dimensional formats: quickly add, subtract, multiply,
divide and convert in feet-inches-fractions, decimal feet, decimal
inches, inches and fractions, yards, meters, centimeters, millimeters,
board feet, as well as square and cubic formats.
- Handles all fractions-1/2's, 1/4's,
1/8's, 1/16's, 1/32's, 1/64's
Work in fractions for all sorts of dimension problems. You can even
set fraction denominators to display your desired accuracy (in above
fraction formats).
- Complete Right-Angle Solutions
Instant square-ups, slopes and rafter lengths.
No more formulas or memorization of Pythagorean theorem! Pitch, Rise,
Run, Diagonal/Common, Hip/Valley and Jack keys find rafter lengths.
Also solves for lengths of irregular Hip/Valley and Jack rafters, as
well as rafter cutting angles!
- Enhanced Jack Rafters Display
Jack rafter lengths in ascending or descending order for regular- or
irregular-pitched roofs. Or set jacks spaced to mate.
- Automatic Stair Calculations
Finds number of risers, treads, riser height, tread width, and any
underage or overage for stairway layouts. Also calculates an entire
stairway based on the entry of a floor-to-floor rise. Even calculates
stringer length and angle of incline.
- Full Trigonometric Functions
Sine, cosine, tangent, arcsine, arccosine, arctangent are included,
for advanced construction math.
- Complete Circle Solutions
Solves radius, diameter, circumference, circle area, arc length,
degree of arc, chord, circular segments, circular volume, for columns,
post holes, pillars, cylinders, etc.
- Degrees:Minutes:Seconds
Solves precise angle calculations; converts from D:M:S and decimal
degrees.
- Instant Area & Volume Calculations
For fast and accurate material estimates, such as finding volume of
concrete.
- Weight per Volume Key
Lets you convert between weights (lbs, tons, kg) and find weights of
any material (e.g., tons per cubic yard).
- Board Feet
Helps estimate material amounts and costs of lumber.
- "Smart" Fraction
Setting Saves keystrokes by entering preset fraction denominators for
you, from 1/2 to 1/64.
- User-Set Preferences
Allows user to set preferred dimensional formats and customize rafter
calculations.
- Three Memory Storage Keys
Lets you permanently store constants or figures for later use.
- Paperless Tape
Lets you review the last 20 entries, for double-checking answers.
- Standard Calculator
Works as a regular math calculator, for your
