Chapter 20 Data Communications 0. Chapter 21 Program Library 0. Appendix 0. Index 0. We recommend that you download the large PDF files that are available from this site and view them off-line.

Align your mouse pointer with the link to the PDF file that you want. If you are running Windows, right-click your mouse. Be sure to pay attention to the input cursor position as you input values and data. S When the calculation does not fit within the display window. Arrows appear at the left, right, top, or bottom edge of the display to let you know when there is more of the calculation off the screen in the corresponding direction.

When you see an arrow, you can use the cursor keys to scroll the screen contents and view the part you want. Certain types of expressions can cause the vertical width of a calculation formula to be greater than one display line.

The maximum allowable vertical width of a calculation formula is about two display screens dots. You cannot input any expression that exceeds this limitation. A value or an expression that you have already input can be used as the argument of a function. Move the cursor so it is located directly to the left of the part of the expression that you want to become the argument of the function you will insert.

Press V to insert the function. As shown above, the value or expression to the right of the cursor after INS are pressed becomes the argument of the function that is specified next. The range encompassed as the argument is everything up to the first open parenthesis to the right, if there is one, or everything up to the first function to the right sin 30 , log2 4 , etc.

UNDO again. After pressing to clear an expression you have input, pressing? UNDO will restore what was on the display before you pressed. If you press C during input and then press? UNDO , the cursor will return to where it was before you pressed C.

UNDO while the keyboard is alpha-locked will perform the same delete operation as the key alone. Be sure to always input a multiplication sign in this case. In this case, use parentheses to keep the key operations separate.

Example: 3 2 —1 BV x —1. Up to 30 sets of calculation expressions and results are maintained. You can also edit the calculation expressions that are maintained by the history function and recalculate.

This will recalculate all of the expressions starting from the edited expression. If history contents include operations that use the answer memory, editing a calculation may affect the answer memory value used in subsequent calculations. You can copy a function, command, or other input to the clipboard, and then paste the clipboard contents at another location.

Use the cursor keys to move the cursor to the line you want to copy. Press MAT to display the following menu. The following operation is a continuation of the example calculation on the previous page. The dot value is normally calculated automatically from the minimum and maximum values. Changing the dot value causes the maximum to be calculated automatically. The following are the selections available in the program PRGM menu. The functions assigned to the function keys are the same as those in the Comp mode.

The following procedure shows how to change a setup. Select the icon you want and press U to enter a mode and display its initial screen. Use the D and A cursor keys to move the highlighting to the item whose setting you want to change. Press the function key to that is marked with the setting you want to make. After you are finished making any changes you want, press to exit the Setup screen. This section details the settings you can make using the function keys in the Setup screen.

S Frac Result fraction result display format. S Func Type graph function type. Pressing one of the following function keys also switches the function of the T key. S Draw Type graph drawing method. S Derivative derivative value display. S Coord graph pointer coordinate display. S Grid graph gridline display. S Label graph axis label display. S Stat Wind statistical graph V-Window setting method. S Resid List residual calculation. S List File list file display settings. S Graph Func function display during graph drawing and trace.

S Dual Screen dual screen mode status. S Simul Graph simultaneous graphing mode. S Background graph display background. S Sketch Line overlaid line type. S Variable table generation and graph draw settings. Otherwise, an error occurs.

Any time while operating the calculator, you can capture an image of the current screen and save it in capture memory. Input a value from 1 to 20 and then press U. Enter a capture memory number in the range of 1 to 20, and then press U.

To exit the image display and return to the screen you started from in step 1, press. If you keep having problems when you are trying to perform operations, try the following before assuming that there is something wrong with the calculator.

Press K to return to the Main Menu. Now enter the correct mode and perform your calculation again, monitoring the results on the display.

The calculator backs up user data main memory when you turn power off and loads the backed up data when you turn power back on. This means that if you press the RESTART button after you edit a program, graph function, or other data, any data that has not been backed up will be lost. Use reset when you want to delete all data currently in calculator memory and return all mode settings to their initial defaults.

Before performing the reset operation, first make a written copy of all important data. If the following message appears on the display, immediately turn off the calculator and replace batteries as instructed. If you continue using the calculator without replacing batteries, power will automatically turn off to protect memory contents. Once this happens, you will not be able to turn power back on, and there is the danger that memory contents will be corrupted or lost entirely. The result is rounded to a 10digit mantissa before it is displayed.

Use Rnd of the Numeric Calculation Menu NUM page to round the displayed value off to the number of decimal place and significant digit settings. This calculator employs true algebraic logic to calculate the parts of a formula in the following order:. With these functions, the value is entered and then the function key is pressed.

With these functions, the function key is pressed and then the value is entered. Abbreviated multiplication format in front of Type A functions, Type C functions, and parenthesis. Permutation, combination n P r , n C r Metric conversion commands. A composite function can consist of up to five functions. S Calculation Result Display Range with. Display of a calculation result in format is supported for result with in up to two terms. Calculation results in format take one of the following forms.

I Multiplication Operations without a Multiplication Sign. Exceeding a specified input or calculation range, or attempting an illegal input causes an error message to appear on the display. Further operation of the calculator is impossible while an error message is displayed.

Press to clear the error and return to normal operation. Each time you press a key, either one byte or two bytes is used. This calculator comes with 28 variables as standard.

You can, however, change the color of comment text to orange or green. Example: To draw a sine curve 1. If you press! Quick-Start is not a complete tutorial, but it takes you through many of the most common functions, from turning the power on, to specifying colors, and on to graphing complex equations.

Each step of the examples in Quick-Start is shown graphically to help you follow along quickly and easily. OFF To turn power off, press! To select the RUN Mode 1.

Press m to display the Main Menu. Use This is the initial screen of the RUN mode, where you can perform manual calculations, and run programs. With formulas that include mixed arithmetic operators and parentheses, the calculator automatically applies true algebraic logic to calculate the result. Press o to clear the calculator. Built-In Functions This calculator includes a number of built-in scientific functions, including trigonometric and logarithmic functions.

Be sure that you specify Deg degrees as the angle unit before you try this example. Press o. SET UP 2. Press degrees as the angle unit.

Press J to clear the menu. Press o to clear the unit. This recalls the calculation so you can make changes or re-execute it as it is.
