EL-520W (TINSExxxxEHZZ)_ENGLISH_1Metric ConversionsSee the quick reference card and the English manual reverse side.Unit conversions can be performed in the normal mode (when notset to binary, pental, octal, or hexadecimal), equation mode andstatistics modes.Calculations Using Engineering PrefixesCalculation can be executed in the normal mode (excluding N-base) using the following 9 types of prefixes.Modify FunctionCalculation results are internally obtained in scientific notationwith up to 14 digits for the mantissa. However, since calculationresults are displayed in the form designated by the display nota-tion and the number of decimal places indicated, the internalcalculation result may differ from that shown in the display. Byusing the modify function, the internal value is converted to matchthat of the display, so that the displayed value can be usedwithout change in subsequent operations.Solver FunctionThe x value can be found that reduces an entered equation to “0”.• This function uses Newton’s method to obtain an approxima-tion. Depending on the function (e.g. periodic) or ‘Start’ value,an error may occur (Error 2) due to there being no convergenceto the solution for the equation.• The value obtained by this function may include a margin oferror. If it is larger than acceptable, recalculate the solutionafter changing ‘Start’ and dx values.• Change the ‘Start’ value (e.g. to a negative value) or dx value(e.g. to a smaller value) if:• no solution can be found (Error 2).• more than two solutions appear to be possible (e.g. a cubicequation).• to improve the arithmetic precision.• The calculation result is automatically stored in the X memory.[Performing Solver function]Q Press m0.

Integral calculation (Simpsons rule):
Differential calculation:[When performing integral calculations]Integral calculations, depending on theintegrands and subintervals included, requirelonger calculation time. During calculation, Cal-culating! will be displayed. To cancel calcula-tion, press ª. Note that there will be greaterintegral errors when there are large fluctua-tions in the integral values during minute shift-ing of the integral range and for periodic func-tions, etc., where positive and negative inte-gral values exist depending on the interval.For the former case, divide integral intervalsas small as possible. For the latter case,separate the positive and negative values.Following these tips will allow results of calculations with greateraccuracy and will also shorten the calculation time.Random FunctionThe Random function has four settings for use in the normal orstatistics mode. (This function cannot be selected while using theN-Base function.) To generate further random numbers in succes-sion, press ®. Press ª to exit.The generated pseudo-random number series is stored in memoryY.

In the binary, pental, octal, and hexadecimal systems, fractionalparts cannot be entered. When a decimal number having a frac-tional part is converted into a binary, pental, octal, or hexadeci-mal number, the fractional part will be truncated. Likewise, whenthe result of a binary, pental, octal, or hexadecimal calculationincludes a fractional part, the fractional part will be truncated. Inthe binary, pental, octal, and hexadecimal systems, negative num-bers are displayed as a complement.Time, Decimal and Sexagesimal CalculationsConversion between decimal and sexagesimal numbers can beperformed, and, while using sexagesimal numbers, conversion toseconds and minutes notation. The four basic arithmetic opera-tions and memory calculations can be performed using thesexagesimal system.

An attempt was made to divide by 0 (or an intermediate calculationresulted in zero).The calculation ranges were exceeded while performing calculations.Depth error (Error 3):The available number of buffers was exceeded. (There are 10 buffers*for numeric values and 24 buffers for calculation instructions).*5 buffers in STAT mode and complex number mode.Data items exceeded 100 in the statistics mode.Equation too long (Error 4):The equation exceeded its maximum input buffer (142 characters).An equation must be shorter than 142 characters.Equation recall error (Error 5):The stored equation contains a function not available in the modeused to recall the equation. For example, if a numerical value withnumbers other than 0 and 1 is stored as a decimal, etc., it cannot berecalled when the calculator is set to binary.Memory over error (Error 6):Equation exceeded the formula memory buffer (256 characters in totalin F1 - F4).Calculation RangesWithin the ranges specified, this calculator is accurate to ±1of the least significant digit of the mantissa. However, acalculation error increases in continuous calculations dueto accumulation of each calculation error. (This is the samefor y
, etc., where continuous calculations areperformed internally.)Additionally, a calculation error will accumulate and becomelarger in the vicinity of inflection points and singular pointsof functions.Calculation ranges
~ ±9.999999999×10
and 0.If the absolute value of an entry or a final or intermediate result of acalculation is less than 10
, the value is considered to be 0 incalculations and in the display.BATTERY REPLACEMENTNotes on Battery ReplacementImproper handling of batteries can cause electrolyte leakage orexplosion. Be sure to observe the following handling rules:Replace both batteries at the same time.Do not mix new and old batteries.Make sure the new batteries are the correct type.When installing, orient each battery properly as indicated in thecalculator.Batteries are factory-installed before shipment, and may be ex-hausted before they reach the service life stated in the specifica-tions.Notes on erasure of memory contentsWhen the battery is replaced, the memory contents are erased.Erasure can also occur if the calculator is defective or when it isrepaired. Make a note of all important memory contents in caseaccidental erasure occurs.When to Replace the BatteriesIf the display has poor contrast or nothing appears on the displayeven when ª is pressed in dim lighting, it is time to replace thebatteries.CautionsFluid from a leaking battery accidentally entering an eye couldresult in serious injury.
