[. . . ] 1234. [ +/­ ] Sign Change Key Press [ +/­ ] to change the displayed number from positive to negative or from negative to positive. MEMORY KEYS [ MR ] Memory Recall Key Press [ MR ] to display the contents of the memory. [ X M ] Memory Store Key Press [ X M ] to store the displayed value into memory. Any previous value in memory is automatically erased. -E2- [ M+ ] Memory Plus Key Press [ M+ ] to total the current calculation and add the result to the value already in memory. [. . . ] [ ab c x ], any number [ y ], and [ = ] to ], [ 2ndF ] [ d ] Fraction key e ab c Pressing by [ ] can enter a fraction or convert a fraction to a decimal number. Pressing by [ 2ndF ] [ d ] can convert a mixed e number to an improper fraction and vice versa. [ CONST ] Physics Constant Key This calculator enables you to perform calculations with 15 built­in -E5- physics constants. Just pressing [ CONST ] key continuously can show the following symbols and values. Symbol Meaning Value c g G Vm NA R e me mp mn u h k 0 0 Speed of light Acceleration of gravity Gravitational constant Molar volume of ideal gas Avagadro's number Molar gas constant Elementary charge Electron mass Proton mass Neutron mass Unified atomic mass Plank constant Boltzmann constant Magnetic permittivity Dielectric permittivity 299792458 m / s 9. 80665 m s ­2 6. 6725985 x 10 ­11 N m 2 kg ­2 0. 0224141 m 3 mol ­1 6. 0221367 x 10 23 mol ­1 8. 3145107 J / K mol 1. 6021773 x 10 ­19 C 9. 1093898 x 10 ­31 kg 1. 6726231 x 10 ­27 kg 1. 6749286 x 10 ­27 kg 1. 6605402 x 10 ­27 kg 6. 6260755 x 10 ­34J.

PGM appears on the display and the previous contents of program memory are cleared. [ RUN ] Compute Key Specify Variable Key Temporarily Halt Calculation Key Runs the recorded program. [ 2ndF ] [ [x] ] Lets you have the calculator wait for an entry during a program. [ 2ndF ] [ HALT ] Temporarily halts a program so you can view the intermediate results or interrupt calculation. STATISTICAL KEYS (USE IN THE STAT MODE ONLY) [ 2ndF ] [ STAT ] Statistical Mode Select Key Sets the calculator to statistical calculation mode. [ 2ndF ] [ CAD ] Statistical Register Clear Key Clears the statistical calculation registers. -E6- [ DATA ], [ DEL ] Data Entry and Delete Key In the STAT mode, enter data by pressing the desired numbers, then [ DATA ]. If you enter incorrect data and do not notice your mistake until you press [ DATA ], enter the same incorrect data and then press [ DEL ] to delete that incorrect data. [ x ] Arithmetic Mean Key Calculates the arithmetic mean ( x ) of the data. [ 2ndF ] [ ] Population Standard Deviation Key Calculates the population standard deviation of the data. [ s ] Sample Standard Deviation Key Calculates the sample standard deviation of the data. x ] Sum of Value Key Calculates the sum of the square value ( Calculates the sum of the value ( x ) of the data. [ n ] Number of Data Key Displays the number of data (n) entries. The Display Indicators showed on the display to indicate you the current status of the calculator. STAT M ­ E PGM CONST GRAD RAD DEG BUSY : Indicates the statistical mode. : Appears to the left of the mantissa or exponent to indicate that the respective value is negative. : Indicates the deviation value -E7- 2F HYP ( : Appears when the second function has been selected. (Even if the number of levels is within 6, an error might occur if you are using memories Ka or Kb, or program memories. ) · You try to use [ 2ndF ] [ Ka x k ] or [ 2ndF ] [ Kb x k ] while memories -E9- Ka and Kb are being used for low­priority calculation storage. · You make a calculation that is out of the range for functional and statistical calculations. [. . . ] You can program your calculator to give you interim values in your formula also. While programming the calculation (in PGM mode), -E15- press [ = ] when you reach the point where you want the interim value displayed. Then press [ 2ndF ] [ HALT ] and continue entering your formula in the usual way. When you run the program, press [ RUN ] after the calculator dispalys an interim value to resume the program. [. . . ]
