3.1 Direct Algebraic Logic (D.A.L.)

The calculator uses Direct Algebraic Logic (D.A.L.), which allows you to input equations exactly as they are written. For example, to calculate sin(30), you would press పాపం, అప్పుడు 30, and finally =.

3.2 Display and Modes

The 12-digit, 2-line LCD display shows both the input expression and the result simultaneously. The calculator supports two main modes:

• సాధారణ మోడ్: Used for general arithmetic, scientific, and engineering calculations.
• Statistical Mode (STAT): Used for statistical computations, including 1-variable and 2-variable statistics. To switch modes, press the మోడ్ button and select the desired option.

3.3 ప్రాథమిక విధులు

Common functions are directly accessible on the keypad:

• Numeric Keypad (0-9, .): సంఖ్యలను నమోదు చేయడానికి.
• అంకగణిత ఆపరేటర్లు (+, -, ×, ÷): For basic calculations.
• = (సమానం): To display the result of a calculation.
• ON/C (On/Clear): Turns the calculator on and clears the current entry.
• ఆఫ్: కాలిక్యులేటర్‌ను ఆఫ్ చేస్తుంది.

3.4 శాస్త్రీయ విధులు

The calculator includes 272 functions. Many advanced functions are accessed using the 2వ ఎఫ్ (second function) key or the ఆల్ఫా కీ.

• Trigonometric Functions (sin, cos, tan): For sine, cosine, and tangent calculations. Inverse functions (sin^-1, కాస్^-1, కాబట్టి^-1) are accessed via 2వ ఎఫ్.
• Logarithmic Functions (log, ln): Common and natural logarithms.
• Power and Root Functions (x², x³, √, y^x): For squares, cubes, square roots, and general powers.
• Memory Functions (STO, RCL, M+, M-): Store, recall, add to, or subtract from memory. The calculator has 8 temporary memory buttons.
• Constants (π): The value of Pi.
• Angle Units (DRG): Cycles through Degree, Radian, and Gradian modes.
• గణాంక విధులు: దీని ద్వారా యాక్సెస్ చేయబడింది STAT VAR or within Statistical Mode for 1-variable and 2-variable statistics.

Refer to the markings above and below the keys for secondary and alpha functions.

4. నిర్వహణ

Proper care and maintenance will extend the life of your Sharp Scientific Calculator EL-531XTB-WH.

4.1 శుభ్రపరచడం

To clean the calculator, gently wipe the surface with a soft, dry cloth. For stubborn dirt, slightly dampen the cloth with water. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the casing లేదా డిస్ప్లే.

4.2 నిల్వ

When not in use, store the calculator in its protective hard case to prevent scratches and damage from impacts. Avoid exposing the calculator to extreme temperatures, high humidity, or direct sunlight for prolonged periods.

4.3 బ్యాటరీ భర్తీ

The calculator uses a Lithium Ion battery as a backup power source. While the calculator is twin-powered and relies heavily on solar energy, the battery ensures operation in low light. If the display becomes dim or erratic in low light, the battery may need replacement. Refer to the battery compartment on the back of the calculator for specific instructions on how to open and replace the battery. Ensure the calculator is turned off before attempting battery replacement.

5. ట్రబుల్షూటింగ్

If you encounter issues with your calculator, refer to the following common problems and solutions.

5.1 Calculator Does Not Turn On

• లైటింగ్ తనిఖీ చేయండి: Ensure there is sufficient light for the solar panel to operate. Try moving the calculator to a brighter area.
• బ్యాటరీ తనిఖీ: If operating in low light, the backup battery may be depleted. Consider replacing the Lithium Ion battery.
• Press ON/C: మీరు నొక్కినట్లు నిర్ధారించుకోండి ON/C బటన్ గట్టిగా.

5.2 Display Shows Error or Unexpected Results

• ఎంట్రీని క్లియర్ చేయండి: నొక్కండి ON/C to clear the current calculation.
• చెక్ మోడ్: Verify that the calculator is in the correct mode (Normal or STAT) for your calculation. Press మోడ్ మార్చడానికి.
• రీసెట్ ఫంక్షన్: If the calculator behaves erratically, a full reset may be necessary. Locate the రీసెట్ చేయండి button (often a small, recessed button requiring a thin object like a paperclip to press) and press it. Note that this will clear all memory and settings.

5.3 Keys Are Unresponsive

• క్లీన్ కీలు: Ensure no debris is lodged under the keys. Gently wipe the keypad.
• పవర్ సైకిల్: కాలిక్యులేటర్‌ను ఆఫ్ చేసి, ఆపై మళ్ళీ ఆన్ చేయండి.
