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]

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).

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] [/] .
User’s Guide – 15
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. Entries of
higher accuracy values will be rounded
to the nearest fraction of the accuracy
setting (for example, for a fraction level
setting of 1/16, an entry of 5 [ / ] 32 [=]
will result in a display of 3/16).
Flashing Denominator
Your calculator can be set to flash the
denominator (bottom) when entering
fractions by pressing [Conv] [/] . In this
way, you can see what fractional accuracy level is set. Pressing [Conv] [/]
again will turn the flashing denominator off. This is a permanent setting that
will remain until revised or reset.
16 – Pocket Handyman®IV
“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:
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).

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 3
fraction bar —
denominator 16
For all other units of measurement, you
can only enter whole numbers or decimal numbers. You cannot enter combinations of units (for example, you
cannot enter 12 meters 6 centimeters 4
millimeters).

Squaring Up
Assume you want to “square-up” forms
for a concrete foundation measuring 45
feet 6 inches by 24 feet 4 inches. In order
for the forms to be square, what should
both of the diagonal measurements be?
(You can use the Pythagorean theorem to
solve the next two problems. See the diagram at the bottom of the next page.)

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.
Auto-Range – If a calculation results in
an answer that exceeds the standard 7digit range of the display, the answer
will be automatically displayed in a larger unit of measurement (instead of
showing “ERROR”). For example,
“10,000,000 mm” cannot be displayed
because it is out of the range of the 7digit display, so “10,000 m” will be displayed instead. This auto-ranging also
applies to other dimensional units, such
as inches to feet, feet to yards, etc.
40 – Pocket Handyman®IV
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). Should the display
become very dim or erratic, replace the
battery.
WARNING: Please use caution when disposing of your old batteries as they contain
hazardous chemicals.
The calculator is designed to shut itself
off after about 8-12 minutes of non-use.
Values in memory or on the display will
be cleared.
Full Reset/All–Clear –Your calculator is
equipped with a special two-key
sequence – [Conv] [x] – to clear all
memory registers to their initial default
values.
