INTRODUCTION

If you build or design things you know the importance of working with accurate dimensions. The most frustrating and costly construction headaches can usually be traced to dimensional errors.

The INCH

MATE

PRO is part of the new generation of Sonin Feet-Inch-fraction Calculators helping people who work with dimensions to simplify difficult and tedious calculations.

KEY PAD INFORMATION

Reduced Fraction Mode

Your calculator is set to Reduced Fraction mode which give the most accurate result (to the /64th). To change your results to a Fixed Fraction you must press [2ND] [2] and desired denominator. The FIX icon will blink. To confirm your selection press [2ND] again.

Example: To change to /8th fixed fraction:

Press

Remember: The PITCH of a roof equals its RISE in INCHES over a RUN of 12" thus a 4/12 roof has a SLOPE of 4". (when entering SLOPE always use inches) In Metric  pitch is expressed in millimeters over 1,000 millimeters of run.

Chaining

Your calculator utilizes chaining logic allowing you to carry out successive intermediate operations using the [=] key to finalize operations. Since the chaining logic works from left to right, you must use care when combining operation such as addition and multiplication by first addressing operations within brackets.

Example: 1 + 2 x 3 + 4 = 13 Enter the values and operators as they are written and press [=] to get the answer.

Example: (1 + 2) x (3 + 4) = 21 Enter 1 [+] 2 [=] [M+] Then enter 3 [+] 4 [x] [RCL] [M+] [=]

NOTE: To recall and remove from memory press [RCL] [RCL]. To recall & keep in memory storage press [RCL] [M+].

Error/Overflow

An error/overflow condition occurs when the result of a calculation has more than 7 digits to the left of the decimal point, or when you attempt to divide a value by zero or calculate mixed units that are not alike. An Error condition is indicated by the "Error" displayed. You must clear the calculator display by pressing [CE/CLR] before continuing operations. Clearing an Error condition will not clear values stored in the memory registers.

Auto-Range

If the input or calculation result with small units is out of the 7 digit range of the display, the answer will be expressed in

- 26 -

REFERENCE

the next larger units instead of showing "Error"

Care

Dont leave calculator in direct sunlight for long periods, or store it where excessive temperatures are possible. Dont leave the calculator on when not in use (NOTE- To save the battery, calculator will turn off automatically after 10-12 minutes of inactivity, at which time the displayed value and memory contents will be cleared.

Battery

This unit requires one 3V lithium battery (CR2016 or equivalent). The average battery operating life is 1000 hours. When the display slows down and/or becomes dim, it is time for a new battery.

To change the battery

1.) Turn power off.

2.) Remove screw from battery lid & slide cover off.

3.) Before removing the battery, be sure to touch a metal object. This is to avoid any accidental discharge of static electricity, which may harm the circuit board.

4.) Install new battery with the (+) side up.

Resetting Your Calculator

To reset your calculator, turn unit over and see RESET. Press with point of ball point pen. You calculator is now reset.

NOTE: RESETTING YOUR CALCULATOR WILL ERASE ANYTHING IN MEMORY OR PAPERLESS TAPE.
