FEATURES (1) Normal operations. y y Four operation (+, –, x, ?), x , x , auto-constant, parenthesis, percentage. (2) Memory calculation (X>M, MR, M+). (3) General mathematical function: Trigonometric (3) Arctrigonometric (3) Logarithmic (2) Exponential (2) Square Power Square Root Cube Root Root ? Parenthesis Reciprocal EXP +/– SCI Factorial DEG, RAD, GRAD Degree, minute, second conversion (2) FIX X-Y RND Coordinate conversion. (4) Binary, octal, decimal and hexadecimal mode. Mutual conversions and calculations of binary, octal, decimal, and hexadecimal numbers. (5) Memory protection when power off. (6) An automatic power off feature to preserve battery life. (7) Statistics calculations. • Number of sample (n). 2 • Total of square of all data (?x ). • Average ( x ). • 2 kinds of the standard deviation (?n–1, ?n). • Total of all data (?x). (8) 2-variable function polar-rectangular coordinate conversion. THE KEYBOARD AND OPERATING CONTROLS SD (1) [ON/C ] : 1. Power on and clear an error condition. 2. Set and clear the statistics mode. - E2 - SR135_English_090326.rtf SIZE : 140x75mm SCALE 2:1 2009/3/26
x! (2) [CE ] : 1. Clear entry key. 2. Factorial function (x!). x! = n x (n–1) x (n–2) x (n–3) x .....x 2 x 1 (3) [OFF] : Power off key. (4) [SHIFT] : This is the key for specifying the second function. When this key is pressed, the special display “SHIFT” lights. When this key press twice continuously, the second function mode releas. (5) [DRG ] : a. Pressing this key will change the mode of angle unit sequentially DEG RAD GRAD and display it on LCD. b. Pressing this key after [SHIFT] key shall change the mode of angle and shall convert the displayed data. DEG > RAD : RAD = DEG x ?/180 RAD > GRAD : GRAD = RAD x 200/? GRAD > DEG : DEG = GRAD x 180/200 (6) [0] ~ [9] : Press these keys in their logical sequence to enter numbers. RND (7) [ ] : a. Use to set the decimal point when entering numbers. b. When press as the first number, it is regarded as [0] and [ • ] keys are pressed. c. Random as a second function. Pressing this key shall display the random number. The range of random number is 0.000~0.999. (8) [+/–] : a. In setting data in the mantissa section, this key reverse code in the mantissa section similarly for exponent section, it reverse code in the exponent section. b. For the operation result, this key reverse code in the mantissa section. (9) [+], [–], [x], [ ? ], [ ( ], [ ) ] a. When the key operations are performed by these keys according to a numerical expression, a result of operation is obtained according to mathematical priorities. Priorities discriminated are: 1) 1-variable function. 2) Expression in "( )"; (The most inner expression has priority in case of multiple parenthesis) y 3) x , y x 4) x, ? 5) +, – - E3 - SR135_English_090326.rtf SIZE : 140x75mm SCALE 2:1 2009/3/26
