Core Functional Parameters
Calculation Functions: 240 scientific calculations, supporting trigonometric functions, logarithms, square roots, factorials, fractions, coordinate conversions, and statistical calculations (SD/REG mode), suitable for junior high school algebra, geometry, high school functions, and physics/chemistry calculation problems.
Button Layout: Standard 82ms classic layout, with SHIFT key, DEL key, AC key to clear, Ans key to save answer, and EXP key. All buttons are labeled in Chinese, making it easy to use.
Screen Configuration: Dual-line LCD screen, displaying formulas up and results down simultaneously, allowing you to review calculation steps and use REPLAY to correct mistakes.
Protective Design: Comes with an original hard sliding cover; when not in use, closing the cover protects against drops, button impacts, and dust, and is convenient for backpack storage.
Power Supply: Built-in button battery, durable and long-lasting, requiring no frequent battery replacements for a school year of regular use.
Applicable Scenarios
Daily Classroom Use: Middle school math, physics and chemistry in-class exercises, homework calculations
Entrance Exams: Junior high school entrance exams, high school graduation exams, academic level tests (suitable for compliant exam venues)
Extracurricular Use: Beginner accounting, adult self-study exams, simple engineering calculations
Advantages of the Dual-Unit Set
Best Value: Buying two units together is more cost-effective than buying them individually; convenient for stocking up, group buying with classmates, or sharing between two children in the family
Emergency Backup: If one unit runs out of power or is damaged, the other can immediately take over, ensuring uninterrupted use during exams
Portable and Separate: Both units have independent sliding covers, making them easy to store separately in backpacks or pencil cases
Usage Tips
Press ON to turn on; AC key clears all data; DEL deletes single characters.
Use the REPLAY key to view complex formulas without re-entering them.
Close the sliding cover when not in use for extended periods to reduce power consumption.
