1. Introduction and Overview
The Sharp EL520XTBBK is an advanced 2-line scientific calculator designed for a wide range of mathematical and scientific applications. It features a Direct Algebraic Logic (D.A.L.) display, allowing calculations to be entered and displayed in a natural, textbook-like format. This calculator is ideal for students and professionals in fields such as general math, science, pre-algebra, algebra I & II, geometry, trigonometry, statistics, biology, chemistry, and physics.
The calculator operates on a twin power system, utilizing both solar energy and battery backup to ensure reliable performance. It comes with a durable, gloss black finish with white accents and includes a protective hard case for portability and protection.

2. Орнотуу жана кубат
2.1 Кубат булагы
The EL520XTBBK calculator is equipped with a dual power system: solar power and battery backup. The solar panel, located at the top of the calculator, provides power in well-lit environments. In low-light conditions or when solar power is insufficient, the calculator automatically switches to battery power. No user intervention is required for power source selection.
2.2 Күйгүзүү/өчүрүү
- Калькуляторду иштетүү үчүн басыңыз ON/C баскычы.
- Калькуляторду өчүрүү үчүн баскычын басыңыз 2-чи Франс баскычынан кийин ӨЧҮРҮҮ button (which is typically the same as ON/C, indicated by an orange 'OFF' label above it). The calculator also features an auto-power-off function to conserve battery life after a period of inactivity.
3. Иштөө нускамалары
3.1 Түз алгебралык логика (ТАЛ)
The D.A.L. system allows you to input equations exactly as they are written, simplifying complex calculations. For example, to calculate sin(30), you would press күнөө, анда 30, анан =. The calculator displays the expression as you enter it, making it easy to verify your input.
3.2 Basic Arithmetic and Scientific Functions
Perform standard operations using the number keys (0-9), decimal point (.), and operators (+, -, ×, ÷). The = key executes the calculation.
Access scientific functions such as trigonometric (күнөө, cos, тан, хип), logarithmic (журнал, ln), and exponential (Exp, 10x, ex) functions directly or by using the 2-чи Франс key for secondary functions. The x2, x3, √, жана yx keys are available for powers and roots.
3.3 Статистикалык эсептөөлөр
The calculator supports 1-variable and 2-variable statistical calculations. To enter statistical mode, press РЕЖИМ and select the appropriate statistical option. Data entry and calculation of mean, standard deviation, and other statistical values are performed using dedicated statistical keys and menus.
3.4 Теңдемелерди чечүүчүлөр
The EL520XTBBK includes a 3-variable linear equation solver. Refer to the detailed manual for specific steps on how to input coefficients and solve systems of linear equations.
3.5 Эстутум функциялары
The calculator features 8 temporary memory buttons and 4 formula memory buttons. Use СТО to store values into memory and RCL to recall them. The M+ жана M- keys allow for direct addition or subtraction to the independent memory.
3.6 Физикалык константалар жана метрикалык конвертациялар
Access a library of built-in physical constants and perform various metric conversions using the dedicated functions. Consult the full user manual for a complete list of available constants and conversion types.
3.7 Demonstration of Features (Similar Model)

4. Техникалык тейлөө
4.1 Тазалоо
Калькуляторду тазалоо үчүн жумшак, кургак чүпүрөктү колдонуңуз. Абразивдүү тазалагычтарды, эриткичтерди же спиртти колдонбоңуз, анткени булар вasing or display. Avoid getting moisture into any openings.
4.2 Сактоо
Колдонулбаган учурда, дисплей менен баскычтар чийилип калбашы жана зыян келтирбөө үчүн калькуляторду коргоочу катуу корпусунда сактаңыз. Калькуляторду экстремалдык температуранын, нымдуулуктун же тике күн нурунун узак убакытка таасир этүүдөн сактаңыз.
5. Кыйынчылыктарды
5.1 Дисплей маселелери
- Бош дисплей: Ensure the calculator is in a well-lit area for solar power or that the battery is not depleted. Press ON/C аны күйгүзүү үчүн.
- Алсыз дисплей: Adjust the contrast setting if available (refer to the full manual for specific instructions). Ensure adequate lighting for solar charging.
5.2 Incorrect Calculations
- Check Input: Verify that the numbers and operations were entered correctly using the D.A.L. display.
- Режим орнотуулары: Ensure the calculator is in the correct mode (e.g., DEG, RAD, STAT) for your calculation. Press РЕЖИМ to cycle through or select modes.
- Кайтаруу: If calculations remain incorrect, a full reset may be necessary. Locate the RESET button (often a small recessed button requiring a thin object like a paperclip) and press it. Note that this will clear all memory and settings.
