User manual SHARP EL-6390

[. . . ] The RESET operation will erase all data stored in memory and restore the calculator's default settings. · Equations that have one result require an additional eleven characters' worth of memory to store in order to hold the result. · In addition to the amount of memory needed to store an equation, the WriteView editor will require a certain amount for the sake of display. · Equations also include calculation ending instructions, such as "=". Functions 6 Priority Levels in Calculation This calculator performs operations according to the following priority: Functions preceded by their argument Fractions (1m4, etc. ) (x -1, x 2, n!, etc. ) y x, xr Implied multiplication of a memory value (2Y, etc. ) Functions followed by their argument (sin, cos, 1 etc. ) Implied multiplication of a function (2sin 30, A , etc. ) 4 nCr, nPr ×, ÷ +, - AND OR, XOR, XNOR =, M+, M-, M, DEG, RAD, GRAD, DATA, CD, r, xy, and other calculation ending instructions · If parentheses are used, parenthesized calculations have precedence over any other calculations. · Refer to the calculation examples for each function. · In the Line editor, the following symbols are used: : to indicate an expression's power. [. . . ] · Explosion risk may be caused by incorrect handling. · Do not throw batteries into a fire as they may explode. Sum of squares of samples (x data) Mean of samples (y data) Sample standard deviation (y data) Population standard deviation (y data) Sum of samples (y data) Replacement Procedure 1. Slide the battery cover slightly and lift it to remove. EL-W531/W531G/W535: Remove the used battery by prying it out with a ball-point pen or other similar pointed device. 2) EL-W531H/W531HA: Remove the used battery. EL-W531/W531G/W535: Install one new battery. Make sure the "+" side is facing up. EL-W531H/W531HA: Install one new battery. First insert the "-" side toward the spring. Press the RESET switch (on the back) with the tip of a ball-point pen or similar object. See "Adjusting the Display Contrast". · U does not function in STAT mode. Degree Minute Second 13 Data Entry and Correction Before entering new data, clear the memory contents. 16 Cannot call!· The function or operation stored in definable memory (D1 to D4) cannot be called. An attempt was made to recall a statistical variable from within NORMAL mode. · The equation (including any calculation ending instructions) exceeded its maximum input buffer (159 characters in the WriteView editor or 161 characters in the Line editor). An equation may not exceed its maximum input buffer. Coordinate Conversions · Before performing a calculation, select the angular unit. · The calculation result is automatically stored in the X and Y memories (r or x in X memory, and or y in Y memory). · The results of coordinate conversions will be displayed as decimal numbers even in the WriteView editor. Rectangular coord. Polar coord. 14 Modify Function Decimal calculation results are internally obtained in scientific notation, with up to 14 digits in the mantissa. However, since calculation results are displayed in the form designated by the display notation and the number of decimal places indicated, the internal calculation result may differ from that shown in the display. By using the modify function (@ n), the internal value is converted to match that of the display, so that the displayed value can be used without change in subsequent operations. · When using the WriteView editor, if the calculation result is displayed using fractions or irrational numbers, press U to convert it to decimal form first. Data entry Single-variable data Data _ Data H frequency _ (To enter multiples of the same data) Two-variable data Data x H data y _ Data x H data y H frequency _ (To enter multiples of the same data x and y) Note: Up to 100 data items can be entered. With the singlevariable data, a data item without frequency assignment is counted as one data item, while an item assigned with frequency is stored as a set of two data items. [. . . ] * De hoeveelheid geheugen dat wordt gebruikt om de WriteView editor weer te geven, gemeten in symbolen (met uitzondering van ingevoerde waarden aangeduid in de grafiek met " "). * A WriteView szerkeszt megjelenítési mveleteire használatos memóriaterület, karakterben kifejezve (az ábrán , , " karakterrel jelölt beviteli értékeket nem számítva). * Mnozství pamti vyuzívané pro úcely zobrazení v editoru WriteView, vyjádené poctem znak (vyjma zadaných hodnot, oznacených v grafu znakem , , "). * Den mängd minne som används för visning med WriteViewredigeraren, mätt i antalet tecken (exklusive inmatade värden, vilka anges som " " i tabellen).
