Review: Calculated Industries Tradesman Calc
Quick Facts:
Model: Tradesman Calc, Model Number 4400
Company: Calculated Industries
Type: Scientific, Construction
Years: Introduced 2012
Display: 8 digits
Batteries: Battery, 1 CR2016
Retail Price: $44.99, you can pay lower on internet searches. I paid $29.95 from WalMart.
Memory Registers: 10, Registers 1 through 9, M
Features
* Units and unit conversions
* Right Triangle Calculations
* Ratio Calculations
* Trigonometry
* Geometry Calculations
Other mathematical functions: reciprocal, powers, roots, degrees/degrees-minutes-seconds, parenthesis
The calculator operates in one of two modes: Order and Chain
Order uses order of operations while chain completes calculations as keys are pressed (like a four-function calculator). Order of operations is the default setting.
Fraction settings allow you to set the largest denominator, up to 64.
Unit and Unit Conversions
In keeping with the other construction calculators, the Tradesman Calc offers units and unit conversions. Notice that the shift key is labeled Conv for this purpose. You can easily add, subtract, multiply, and divide measurements. For example to add 4 feet 5 inches with 6 feet 7 1/2 inches, press:
4 [ Feet ] 5 [ Inch ] (Display: 4 - 5 FEET INCH)
[ + ] 6 [ Feet ] 7 [ Inch ] 1 [ / ] 2
[ = ]
Display: 11 - 0 1/2 FEET INCH (11 feet, 1/2 inch)
You can convert the answer to decimal feet like this:
[ Conv ] [ Feet ]
Display: 11.041667 FEET
To convert to Inches:
[ Conv ] [ Inch ]
Display: 132.5 INCH
To meters:
[ Conv ] [ m ]
Display: 3.3655 M
Units also include temperature (°F, °C), weight and mass (lbs, dry oz, tns, kg, grams, metric tons, wt/vol), and length (yds, feet, inch, m, cm, mm Bd Ft).
Right Triangle Calculations
The [ Adj ] (adjacent side), [ Opp ] (opposite side), [ Hyp ] (hypotenuse), and [Angle] (angle and adjacent angle) keys are used to solve right triangle problems. Any two of the variables can be known to solve for everything else. For example:
Known: Adjacent (run): 15 feet, Opposite (rise): 13 feet 8 inches
[Conv] [ × ] (Clear All) (as recommended by Calculated Industries)
15 [ Feet ] [ Adj ]
13 [ Feet ] 8 [ Inch ] [ Opp ]
[Hyp] 20.292308 feet
[Angle] 42.336999°
[Angle] 47.663001° (adjacent angle)
Ratio Calculations
Use the X, Y, and X:Y commands to store and calculate ratios. Example:
For the ratio 5/8 find X when X/18.
5 [Conv] [ Adj ] (X) (stores 5 in X)
8 [Conv] [ Opp ] (Y) (stores 8 in Y)
[Conv] [ Hyp ] (X:Y) Result: 1 = 1.6
18 [Conv] [ Opp ] (Y) (stores 18 in Y)
[Conv] [ Adj ] (X) Result: X = 11.25
Trigonometry
The Tradesman Calc has the trigonometric functions sine, cosine, and tangent, with inverse. All angles are measured in degrees.
Geometry
Geometric calculations includes circles, arcs, and regular polygons (including inside and outside diameter).
Keyboard
The keyboard is a pleasure to use. Aside it being blue (blue is my favorite color), the keys have a pleasant touch and register perfectly. The display is clear with prompts. The Tradesman Calc comes with a hard case cover. On the back of the calculator, there is a slot for a battery and another for user guide.
Verdict
For a trade industries, I recommend this calculator. The calculator has a convenient solvers for common geometry shapes along with unit mathematics. If you are going to purchase the Tradesman Calc, I recommend so shopping for less than retail price.
