Reset operation If the calculator is on but you get unexpected results, press [ MODE ] or ]. If problems persist, press [ 2nd ] [ RESET ]. A message appears asking you to confirm that you want to reset the calculator.
2-digit positive or negative exponent. Results that exceed this limit are displayed in scientific notation. Indicators The following indicators appear on the display to indicate the status of the calculator. Indicator Meaning Values are stored in running memory –...
SCIENG SCIentific or ENGineering display format Number of decimal places displayed is fixed Hyperbolic trig function will be calculated The displayed value is an intermediate result There are digits to the left or right of the display There are earlier or later results that can be displayed. These indicators blink while an operation or program is executing.
If you press [ 2nd ] by mistake, press [ 2nd ] again to remove the 2nd indicator Pressing [ ALPHA ] [ 2nd ] locks the calculator in 2nd function mode. This allows consecutive input of 2nd function keys. To cancel this, press [ 2nd ] again.
[ MRC ]. To clear running memory, press [ MRC ] twice. See Example 4. Standard memory variables The calculator has 26 standard memory variables—A, B, C, D, …, Z—which you can use to assign a value to. See Example 5. Operations with variables include: [ SAVE ] + Variable assigns the current answer to the specified variable •...
memories can be added in this way, giving you a maximum of 59 memories (26 + 33). Note: To restore the default memory configuration—26 memories—specify Defm 0. Expanded memories are named A [ 1 ] , A [ 2 ] etc and can be used in the same way as standard memory variables.

2. An improper argument was used in a command or function. 3. An END statement is missing from a program. LENGTH Er An entry exceeds 84 digits after implied multiplication with auto-correction. OUT OF SPEC You input a negative C NEST Er Subroutine nesting exceeds 3 levels.
You can enter a number in mantissa and exponent format using the • [ EXP ] key. See Example 13. This calculator also provides 11 symbols for input of values using • engineering notation. Press [ 2nd ] [ ENG SYM ] to display the symbols.
When you enter a numeric value or numeric expression and press [ the result is stored in the Answer function, which you can then quickly recall. See Example 19. Note: The result is retained even if the power is turned off. It is also retained if a subsequent calculation results in an error.
To convert from DMS notation to decimal notation, select ° (degrees), ’(minutes), ”(seconds). See Example 27. Trigonometric and Inverse Trigonometric functions The calculator provides standard trigonometric functions and inverse trigonometric functions: sin, cos, tan, sin Note: Before undertaking a trigonometric or inverse trigonometric calculation, make sure that the appropriate angular unit is set.
Defm Memory expansion. Other Functions ( x The calculator also provides reciprocal ( [ x root ( [ ] ), square ( [ x exponentiation ( [ ^ ] ) functions. See Example 32. Unit Conversion You can convert numbers from metric to imperial units and vice versa.
Enter the number you want to convert. Press [ 2nd ] [ CONV ] to display the units menu. There are 7 menus, covering distance, area, temperature, capacity, weight, energy, and pressure. Press [ ] or [ appropriate units menu is shown, then press [ Press [ ] or [ Physics Constants...
Position your cursor where you want the constant inserted. Press [ 2nd ] [ CONST ] to display the physics constants menu. Scroll through the menu until the constant you want is underlined. Press [ ]. (See Example 34.) Multi-statement functions Multi-statement functions are formed by connecting a number of individual statements for sequential execution.
After setting the range, press [ Graph ] and enter the expression to be graphed. See Example 37. Graph ↔ Text Display and Clearing a Graph Press [ G T ] to switch between graph display and text display and vice versa.
This function lets you move a pointer around a graph by pressing [ ]. The x- and y-coordinates of the current pointer location are displayed on the screen. This function is useful for determining the intersection of superimposed graphs (by pressing [ 2nd ] [ X Note: Due to the limited resolution of the display, the position of the pointer may be an approximation.
Press [ variables until you reach the variable you are interested in (see table below). Variable Number of x values or x–y pairs entered. Mean of the x values or y values. Xmax or Ymax Maximum of the x values or y values. Xmin or Ymin Minimum of the x values or y values.
Cpx or Cpy Potential capability precision of the x values or y values, Cpkx or Cpky Minimum (CPU, CPL) of the x values or y values, where CPU is the upper spec. limit of capability precision and CPL is lower spec. limit of capability precision. Parts per million, Defection Per Million Opportunities.
R(t) The cumulative fraction of the standard normal distribution that lies between t and 0. R(t) = 1 – t. Q(t) The cumulative fraction of the standard normal distribution that is greater than t. Q(t) = | 0.5– t |. Regression Calculation There are six regression options on the REG menu: Linear Regression...
You can enter numbers in base 2, base 8, base 10 or base 16. To set the number base, press [ 2nd ] [ dhbo ], select an option from the menu and press [ ]. An indicator shows the base you selected: d, h, b , or o. (The default setting is d: decimal base).
See Array Variables above. Program Type: You must specify in each program the calculation mode that the calculator should enter when executing the program. To perform binary, octal or hexadecimal calculations or conversions, choose BaseN; otherwise choose MAIN.
INPUT memory variable ⇒ Makes the program pause for data input. memory variable = appears on the display. Enter a value and press [ assigned to the specified variable, and the program resumes execution. To input more than one memory variable, separate them with a semicolon (;).
⇒ Each program needs an END command to mark the end of the program. This is displayed automatically when you create a new program. Increment and decrement Post-fixed: Memory variable + + or Memory variable – – Pre-fixed: + + Memory variable or – – Memory variable ⇒...
Select one of the ten program areas (P0123456789) and press [ Enter your program’s commands. • You can enter the calculator’s regular functions as commands. • To enter a program control instruction, press [ 2nd ] [ INST ] and make your selection.
Debugging a Program A program might generate an error message or unexpected results when it is executed. This indicates that there is an error in the program that needs to be corrected. Error messages appear for approximately 5 seconds, and then the •...
To erase all the programs, select ALL. A message appears asking you to confirm that you want to delete the program(s). Press [ ] to move the cursor to Y and then press [ To exit DEL mode, select EXIT from the program menu. Program Examples See Examples 54 to 63.
