FRACTIONAL SETTINGS

When your calculator is in a default condi­tion (battery change or full reset), it is set
to round fractional values to the nearest
1/64th 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 Ç as shown below:

Ç 1 = Fraction Set to 1/16”
Ç 2 = Fraction Set to 1/2”
Ç 3 = Fraction Set to 1/32”
Ç 4 = Fraction Set to 1/4”
Ç 6 = Fraction Set to 1/64”
Ç 8 = Fraction Set to 1/8”

If there is a value on the display, when one
of the functions above is performed the
accuracy level will be temporarily revised.
If the display is cleared, then the accuracy
will be permanently revised.

POCKET REFERENCE GUIDE — 15

PREFERENCE FEATURE

The Ultra Measure Master provides
Preference Settings that allow you to set
fractional accuracy and display features.
The preference settings are displayed
using ® /. Repeated presses of / tog­gle through the different settings while the
+ and – keys are used for revision.
These settings remain set until they are
changed or the calculator is reset.

FRACTIONAL ACCURACY SETTINGS

• Fraction Set to 1/64”

(Default)

• Fraction Set to 1/2”

• Fraction Set to 1/4”

• Fraction Set to 1/8”

• Fraction Set to 1/16”

Whenever the fractional setting is other

appear in the bottom left of the display
when the calculator is turned on. This indi­cates a special fractional setting is stored
within.

Setting Fractional Accuracy

KEYSTROKES DISPLAY

1. Access the Preference Feature:

® / NM 1/64

(Note “1/64” flashing)

2. Scroll through preference options:

/ NM 1/64 INCH

(Note “nm” flashing)

/ EXP On
/ FLSH OFF

3. Change fraction setting to 1/8:

/ NM 0-1/64 INCH
+ NM 0-1/2 INCH
+ NM 0-1/4 INCH
+ NM 0-1/8 INCH

4. Return calculator to normal operation
and verify fraction setting:

o ® / NM 0-1/8 INCH

Setting Fractional Modes
Normal Mode

In Normal Mode, the fractional result is
reduced to its lowest common denominator
(i.e., 8/16 reduces to 1/2).

Fixed Mode

In Fixed Mode, fractional results remain in
the defined accuracy level (i.e., 1/2 will be
shown as 8/16). Entries of higher accuracy
values will temporarily override the fixed
fraction setting.

POCKET REFERENCE GUIDE — 17

USING EXPONENTIAL NOTATION

Your calculator is defaulted to have expo­nential notation set to “on.” Therefore, any
integer value exceeding seven digits will
display in exponential format. When expo­nential notation is deactivated, the calcula­tor adjusts dimensioned values to a higher
unit when the display limit is exceeded
(known as Auto-Ranging). i.e., “10,000,000
mm” exceeds the seven-digit display, so
“10,000 m” is displayed. This auto-ranging
also applies to other dimensional units,
such as inches to feet, feet to yards, etc.

To enter an exponential value, enter the
main value, press s /, then enter the
exponential power.

SETTING FLASHING DENOMINATOR

Your calculator can be set to flash the
fractional denominator while fractions are
entered. The flashing denominator is use­ful as it displays the fractional accuracy
setting.

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 (=).

A. 3 + 2 = 5
B. 3 – 2 = 1
C. 3 x 2 = 6
D. 3 ÷ 2 = 1.5

This feature also makes the calculator sim­ple to use for dimensional math.

Adding or Subtracting Dimensions

1) You can add or subtract two numbers
when the first value entered is labeled
with units of measurement and the
other is just a whole number (no units
of measurement).

2) You can add or subtract numbers
whose units of measurement are within
the same convention. For example,
you can add or subtract kg and
pounds.

3) You cannot add or subtract two num­bers of different conventions, except
for weight and volume.

(Cont’d)

POCKET REFERENCE GUIDE — 20

(Cont’d)

4) The format of the first value you enter
determines the format of the answer.
However, you can use the Ç key to
change to any format desired, provided
that you maintain convention.

Examples:

KEYSTROKES DISPLAY

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

inches:

7 f 3 i 1 / 2 +

1 1 f 4 i = 18

FEET 7-1/2 INCH

2. Add 25 PSF to 12 PSI:

2 5 s d + 1 2 s l =

1753

PSF

3. Add 14 gallons to 52 liters:

1 4 g + 5 2 L = 27.73695 GL

4. Subtract 450 acres from 5 square km:

5 S K – 4 5 0 s 5 =

3.178915

SQ kM

5. Subtract 32 mm from 8 centimeters:

8 c – 3 2 M = 4.8 CM

Multiplying or Dividing Dimensions

1) You can multiply and divide two num-

bers when the first value entered is
labeled with units of measurement and
the other is just a whole number (no
units of measurement).

(Cont’d)

POCKET REFERENCE GUIDE — 21

(Cont’d)

2) You cannot multiply or divide two num-

bers that have different units of meas­urement or different conventions,
except for weight and volume.

3) You can multiply and divide numbers

when their units of measurement are
within or between the linear and area
conventions. For example, you can
multiply kilometers by square feet,
which will give you cubic kilometers.

4) The format of the first value you enter

determines the format of the answer.
However, with the Ç key you can
change to any format you desire, pro­vided that you maintain convention.

Examples:

KEYSTROKES DISPLAY

1. Multiply 5 feet 3 inches by 8 feet 6-1/2

inches:

5 f 3 i x 8 f

6 i 1 / 2 = 44.84375

2. Multiply 50 meters per minute by 12.5:

5 0 s m x 1 2 • 5 = 625 M/M

3. Multiply 33.5 gallons by 2.031:

3 3 • 5 g x 2 • 0 3 1 =

4. Divide 20 feet 3 inches by 9:

5. Divide 30 mph by 2.5:

3 0 s µ ÷ 2 • 5 = 12 MPH

Percent Calculations

The percent key % can be used to find a
percentage of a number or for working
add-on, discount or division percentage
calculations.

MEMORY OPERATION

The

Ultra Measure Master

has ten storage
registers (0 through 9). Memory 0 is a
cumulative memory which operates similar
to a standard µ key, while the other
memories are used for storage only. A
value can be stored in any format, but
attempts to add mixed conventions will
result in an error (the value in memory will
not be revised). Memory 0 will keep its
value until it is revised (as shown below),
or the calculator is shut off. Memories 1
through 9 will keep their values even when
the calculator is shut off. Keystrokes for
operation are as follows:

ENTERING DIMENSIONS AND 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).

ACCURACY/ERRORS
Accuracy/Display Capacity

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 ten digits and
rounded to a seven-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 calculator's ability, it
displays the word “ERROR.” To clear an
error, press the o button twice. At this
point you must determine what caused the
error and re-key the entry. An error also
occurs if you enter a mathematical impos­sibility such as division by zero.

APPENDIX

POCKET REFERENCE GUIDE — 46

Auto-Range

If an “overflow” is created because of an
input and calculation with small units that
are out of the standard seven-digit range
of the display, the answer will be automati­cally expressed in the next larger units
(instead of showing “E

RROR”) — i.e.,

“10,000,000 mm” cannot be displayed
because it is out of the seven-digit display,
so “10,000 m” will be displayed instead.
This auto-ranging also applies to other
dimensional units, such as inches to feet,
and feet to yards, etc.

BATTERY INFORMATION

Your calculator is powered by a single three­Volt Lithium CR-2032 battery. This should
last upwards of 800 hours of actual use
(one year plus for most users). 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.
