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.

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”

• Fraction Set to 1/32”

FRACTION MODES

• Normal Mode (Default)

• Fixed Mode

EXPONENT

• On (Default)

• Off

FLASHING FRACTION

• Off (Default)

Whenever the fractional setting is other than 1/64 normal mode, a star ( ★ ) will 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 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.

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.

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.

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.

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.

2) You cannot multiply or divide two numbers 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.

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.

APPENDIX

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 “E

RROR

.” 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.

OCKET

EFERENCE

UIDE

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 three-

Volt 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.
