INTRODUCING POCKET HANDYMAN® IV Designed for today’s busy woodworkers, hobbyists and do-it-yourselfers, the new Pocket Handyman IV is so simple to use, even first-time users will find it easy to solve all kinds of dimensionrelated problems.
KEY DEFINITIONS [+] [–] [x] [÷] [=] Arithmetic operation keys. [%] Four-function percent key. 0 – 9 and [ • ] Digits used for entering numbers. [Off] — Off Key Turns power off. [On/C] — On/Clear Key Turns power on. If on, pressing once clears the last entry and the display. Pressing twice clears all temporary registers (stored values). [Conv] Used with the dimensional keys to convert between dimensions. Dimensions can only be converted within the same convention (i.e., linear, square or cubic).
[Conv] [ ] — x2 Function Finds the square of the displayed number. The calculator will display an error if you try to find the square of an area or volume value. [M+] — Memory Plus Stores or adds the displayed number to memory. [Conv] [M+] — Memory Minus Subtracts the displayed value from memory. [Rcl] — Recall Key Recalls values stored in any register (i.e., [Rcl] [M+] displays the value stored in memory). [Conv] [Rcl] — Memory Clear Clears the value in memory without changing the display.
[Feet] — Feet Key This is an entry and conversion key. You can enter whole or decimal numbers. You can also use this key to enter values in feet-inch-fraction format: (2 [Feet] 1 [Inch] 1 [/] 2). To convert a displayed value to feet, press [Conv] [Feet]. Repeated presses toggle between feetinches and decimal feet formats. [Inch] — Inch Key This is an entry and conversion key (when used with the [Conv] key). You can enter whole or decimal numbers.
displays the current fractional denominator and accesses the fractional setting mode. See the “Fraction Setting” section for more information. [Cu] — Cubic Key Used with a dimension key (feet, inches, yards, meters, etc.) to identify a volume dimension. Example: 5 [Cu] [Yds]. [Sq] — Square Key Used with a dimension key (feet, inches, yards, meters, etc.) to identify an area dimension. Example: 10 [Sq] [Feet]. [m] — Meters Key This is an entry and conversion key (when used with the [Conv] key).
[Weight] — Weight Key Enters or converts (a volume value) to tons, pounds, metric tons or kilograms. Repeated presses will cycle through these units. [Conv] [%] — Weight per Volume Enters or converts the Weight per Volume setting as Tons/Yard3, Lbs/Yd3, Lb/Ft3, Metric Ton/m3 or kg/m3. Repeated presses will cycle through these settings. [Circ] — Circle Key Used to enter a circular diameter and find the area and circumference.
[Conv] [+] — Pi (π) Internal constant = 3.141593. [Conv] [–] — Change Sign Function Toggles th e sign of a value between positive and negative values. [Rcl] [=] — Paperless Tape Feature Accesses the paperless tape mode. See the “Paperless Tape” section for more information. [Rcl] [x] — Metric Mode Toggle Toggles between Imperial and Metric defaults for the weight per volume factor and the weight key. When you are in Metric Mode, any value in meters will be limited to three decimal places to the right.
OPERATING BASICS 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 3 3 3 [+] [–] [x] [÷] 2 2 2 2 [=] [=] [=] [=] 5 1 6 1.
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] [=] Add 2 feet 1 inch to 11 inches: 2 [Feet] 1 [Inch] [+] 11 [Inch] [=] 36 IN 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.
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] [=] Divide 20 feet 3 inches by 9: 20 [Feet] 3 [Inch] [÷] 9 [=] 52 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.
Memory Functions Whenever the [M+] key is pressed, the displayed value will be added to memory.
How to use memory functions: Steps Keystrokes Display Add to memory 355 [M+] 355. Add to mem. 255 [M+] 255. Recall total mem. [Rcl] [M+] 610. Subt. from mem. 745. 745 [Conv] [M+] Recall total mem. [Rcl] [M+] Replace mem. 50 [Conv] [Rcl] [M+] Recall & clear – 135. [Rcl] [Rcl] 50. 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).
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.
Normal Fractional Mode The default, Normal Mode ([Conv] 7), reduces a fraction to its lowest common denominator (for example, 8/16 reduces to 1/2). If a fraction is entered having a higher fractional accuracy than the current setting, the setting will be temporarily revised to the level of accuracy of the entered value. Fixed Fractional Mode In the Fixed Mode ([Conv] 9), fractional results are displayed in the set fractional value, not reduced.
“Paperless Tape” Feature The “Paperless Tape” feature allows the user to display the last 20 entries. While in the Paperless Tape mode, your display will look similar to this: 04 + 12 INC The display shows the entered or calculated value (12 Inch), sequence number (04), and the math operator (in this case it is “+”) for each entry. As you scroll through the entries, you will see the designators TTL and SUB. “SUB” indicates a subtotal. “TTL” indicates the final total (all subtotals combined).
2. Access the Tape function [Rcl] [=] TTL= 22 FEET 0 INCH 3. Scroll forward from first value to total: [+] 01 4 FEET 0 INCH [+] 02+ 5 FEET 0 INCH [+] 03+ 6 FEET 0 INCH [+] 04+ 7 FEET 0 INCH [+] TTL= 22 FEET 0 INCH 4. Scroll back to last 2 values: [–] 04+ 7 FEET 0 INCH [–] 03+ 6 FEET 0 INCH 5. † Display total and add more values: [=] [+] 2 [Feet] [=] TTL= 22 FEET 0 INCH 22 FEET 0 INCH 24 FEET 0 INCH † Note: At this point, you can press any key twice (except [Off], [+] or [–]) to exit the tape feature.
Clearing the Paperless Tape The paperless tape is cleared: 1) when you press [On/C] [On/C] (clear); 2) when you press [Conv] [x] (all clear); 3) when you turn the unit off.
USING THE POCKET HANDYMAN IV Entering Dimensions & Units When entering feet-inch dimensional values, you must enter the largest dimension first — feet before inches, inches before fractions. To enter fractions of an inch, enter the numerator (value above the line), press [/] (fraction bar key) and then enter the denominator (value below the line). numerator fraction bar denominator 3 — 16 For all other units of measurement, you can only enter whole numbers or decimal numbers.

Calculator Information Accuracy/Display – Your calculator has an eleven digit display. This is made up of seven digits (normal display) and four digits for the fraction. In a standard calculation, each calculation is carried out internally to 10 digits and is rounded to a 7-digit standard display. A 5/4 rounding technique is used to add 1 to the least significant digit in the display if the next non-displayed digit is five or more. If this digit is less than five, no rounding occurs.
Errors – When you make an incorrect entry, or the answer is beyond the range of the calculator, it will display the word “ERROR.” To clear an error condition you must hit the [On/C] button. You must then re-enter the problem. An error will occur if you enter a mathematical impossibility such as division by zero. Battery Information – The calculator is powered by a single 3-Volt Lithium CR2032 battery. This should last upwards of 800 hours of actual use (1 year plus for most people).
