Anleitung Zusammenfassung


Auto power-off function The calculator automatically turns off if it has not been used for approximately 9 minutes. Power can be restored by pressing the [ON/C] key again. Memory contents and the current mode setting (STAT, DEG, CPLX, Base-n,etc) are retained when you turn off the power and when the calculator automatically turns off. Battery replacement The calculator is powered by two alkaline button batteries (GP76A or LR44). If the display becomes dim and difficult to read, the batteries should be replaced as soon as possible. To replace the batteries: 1. Slide the battery cover off and remove the old batteries. 2. Insert new batteries, with positive polarity facing outward. 3. Replace the battery cover and press [ON/C] to turn on the power. The keyboard Most of the keys can perform two functions. 2nd function ...... sin–1 1st function ... sin 1st functions These are functions that are executed when you press a key without first pressing [ 2ndF ]. The function performed is indicated by the label on the key. 2nd functions These are functions that are executed when you press a key after first pressing [ 2ndF ]. The function performed is indicated by the label above the key. When you press [ 2ndF ], the 2ndF indicator appears in the display to indicate that you will be selecting the second function of the next key you press. If you press [ 2ndF ] by mistake, simply press [ 2ndF ] again to remove the 2ndF indicator. Note: [ A ], [ B ], [ C ], [ D ], [ E ], [ F ] are 1st functions in HEX mode. Display Symbols The following symbols, shown on the display, indicate the status of the calculator. DEG or RAD or GRAD: degrees, radians or grads angular unit M A value is in memory CPLX Complex number mode E Overflow or error STAT Statistical mode – Minus 2ndF [2ndF] key pressed ( ) Parentheses calculation CP Precision capability BIN Binary mode CPK Process capability OCT Octal mode . Deviation HEX Hexadecimal mode USL Setting upper limit ED Edit mode LSL Setting lower limit HYP Hyperbolic mode Display Formats The calculator can display numbers in four formats: floating point, fixed point, scientific, and engineering. Floating point format The floating point format displays numbers in decimal form, using up to 10 digits. Any trailing zeros are truncated. If the result of a calculation is too large to be represented by 10 digits, the display automatically switches to scientific format. If the result of a later calculation is small enough to be displayed in less than 10 digits, the calculator returns to floating point format. To set the display to floating point display format: DEG 0. 4. Press [ 2ndF ] [ FIX ] [•] Fixed point format The fixed point, scientific, and engineering formats use a fixed number of decimal places to display numbers. If more than the specified number of decimal places is keyed, the entry will be rounded to the correct number of decimal places. Ex. 1: Fix the display at 2 decimal places, then key in 3.256 1. Press [ 2ndF ] [ FIX ] 2 2. Key in 3.256 [ENTER] DEGDEG 0.00 3.26 If fewer than the set number of decimal places is keyed, the entry will be padded with trailing zeros. Ex. 2: Fix the display at 4 decimal places, then key in 4.23 1. Press [ 2ndF ] [ FIX ] 4 2. Key in 4.23 [ENTER] DEG DEG 0.0000 4.2300 Scientific format In scientific format, the number 891500 is shown as 8.915 . 10 05, where 8.915 is the mantissa and 5 is the exponent of 10. Ex. 3: To display 7132 . 125 in scientific format: 1. Key in 7132 [ . ] 125 [ENTER] 2. Press [ F<>E ] DEG DEG 891500. 8.915 05 You can convert an entry to scientific notation by pressing [EXP] after entering the mantissa. Ex. 4: Key the number 4.82296 . 10 5 DEG 4.82296 05 1. Key in 4.82296 [ EXP ] 5 Engineering format Engineering format is similar to scientific format, except that the mantissa can have up to three digits to the left of the decimal and the exponent is always a multiple of three. This is useful if you have to convert units that are based on multiples of 10 3. Ex. 5: Convert 15V to 15000mV (V = Volts) 1. Key in 15 2. Press [ ENG ] twice. Ex. 6: Convert 15V to 0.015KV (V = Volts) 1. Key in 15 2. Press [ 2ndF ] [ < ] [ 2ndF ] [ < ] DEG DEG DEG DEG 15. 15000. – 03 15. 0.015 03 Order of Operations Each calculation is performed in the following order of precedence: 1. Operations in parentheses. 2. Functions that require pressing the function key before entering a value, for example, [ DATA ] in statistics mode, and [ EXP ]. 3. Functions that require values to be entered before pressing the function key, for example, cos, sin, tan, cos –1, sin –1, tan –1, log, ln, 2 –1 3 x, x , v, ., v, x!, %, RND, ENG, , , and the unit conversion functions. 4. Fractions. 5. +/– 6. xy, Xv 7. nPr, nCr 8. ., . 9. +,– Corrections If you have made a mistake when entering a number and you have not yet pressed an arithmetic operator key, just press [ CE ] to clear the last entry. You can then input the desired number again. Alternatively,you can delete digits one at a ti...
