Power On & Off

Turn the calculator on by pressing the

[On/C] key. To turn it off, press the [Off] key.

Auto Shut-Off

The calculator will turn itself off if it is not used within 8-10 minutes.

Basic Math Operations

Your calculator uses standard chaining logic which simply means that you enter your first value, the operator (+, –, x, ÷), the second value and then the equals sign (=).

3 [+] 2 [=] 5 3 [–] 2 [=] 1 3 [x] 2 [=] 6 3 [÷] 2 [=] 1.5

This feature also makes the calculator simple to use for dimensional math, as shown in the following examples:

OPERATING

BASICS

10 – Pocket Handyman®IV

Adding Dimensions

Add 7 feet 3-1/2 inches to 11 feet 4 inches:

7 [Feet] 3 [Inch] 1[/] 2 [+]

11 [Feet] 4 [Inch] [=] 18 FT 7-1/2 IN

Add 11 inches to 2 feet 1 inch:

11 [Inch] [+] 2 [Feet] 1 [Inch] [=] 36 IN

Add 2 feet 1 inch to 11 inches:

2 [Feet] 1 [Inch] [+] 11 [Inch] [=] 3 FT 0 IN

Note: The format of the first value you enter determines the format of the answer. However, with the [Conv] key you can change to any format you want, provided that you maintain convention.

Subtracting Dimensions

Subtract 3 feet from 11 feet 7-1/2 inches:

11 [Feet] 7 [Inch] 1 [/] 2

[–] 3 [Feet] =] 8 FT 7-1/2 IN

Subtract 32 inches from 81 inches:

81 [Inch] [–] 32 [Inch] [=] 49 IN

Multiplying Dimensions

Multiply 5 feet 3 inches by 11 feet 6-1/2 inches:

5 [Feet] 3 [Inch] [x]

11 [Feet] 6 [Inch] 1 [/] 2 [=] 60.59375 SQ FT

User’s Guide – 11

Multiply 2 feet 7 inches by 10 :

2 [Feet] 7 [Inch] [x] 10 [=] 25 FT 10 IN

Dividing Dimensions

Divide 30 feet 4 inches by 7 inches:

30 [Feet] 4 [Inch] [÷] 7 [Inch] [=] 52

Divide 20 feet 3 inches by 9:

20 [Feet] 3 [Inch] [÷] 9 [=] 2 FT 3 IN

Percentage Calculations

The Percent [%] key is used to find a percent of a number or for working add-on, discount or division percentages. It can be used with any type of number, any dimension (feet, inch, millimeter, etc) and convention (non-dimensioned, linear, square or cubic).

Find 18% of 500 feet:

500 [Feet] [x] 18 [%] 90 FT 0 IN

Add 10% for waste to 137 square feet:

137 [Sq] [Feet] [+] 10 [%] 150.7 SQ FT

Take 20% away from 552 feet 6 inches:

552 [Feet] 6 [Inch] [–] 20 [%] 442 FT 0 IN

Add to mem. 255 [M+] 255.

Recall total mem. [Rcl] [M+] 610.

Subt. from mem. 745 [Conv] [M+] 745.

Recall total mem. [Rcl] [M+] – 135.

Replace mem. 50 [Conv]

[Rcl] [M+] 50.

Recall & clear [Rcl] [Rcl] 50.

The memory function can also be used with dimensional units, as long as they are of the same convention (all linear, square or cubic). The calculator will display the word “ERROR” if you try to enter numbers of different conventions.

14 – Pocket Handyman®IV

Fractional Settings

When you first receive your calculator it is set to its default state. When in this state, fractional values are rounded to the nearest 1/16 of an inch. However, you may program your preference for six different accuracy levels and two different modes (Normal and Fixed), all of which remain in permanent memory until revised or reset.

The fractional level can be revised by using the keystrokes below:

Keystroke Fraction Setting

[Conv] 1 1/1

6 [Conv] 2 1/2 [Conv] 3 1/32 [Conv] 4 1/4

[Conv] 6 1/64

[Conv] 8 1/8

Note: Whenever the calculator is set to anything other than 1/16 normal mode, a star (★) will appear in the bottom left of the display during power up to indicate a special fractional setting has been stored within. The fractional setting can be displayed at any time by pressing [Rcl] [/] .
