Resumen del manual
Larger values are automatically displayed using exponential notation. In the case of decimal value, you can select between two formats that determine at what point exponential notation is used. • NORM 1 With NORM 1, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than two decimal places. • NORM 2 With NORM 2, exponential notation is automatically used for integer values with more than 10 digits and decimal values with more than nine decimal places. — 24 — To switch between NORM 1 and NORM 2 Press F E. There is no indication on the display of which format is currently in effect, but you can determine the setting by performing the following calculation. 1 B 200 B I 5. 03 I NORM 1 format | 0.005 I NORM 2 format • All of the examples in this manual show calculation results using the NORM 1 format. ■When you have a problem... If calculation results are not what you expect or if an error occurs, perform the following steps. 1. F E (COMP mode) 2. F E (DEG mode) 3. F E (NORM mode) 4. Check the formula you are working with to confirm it is correct. 5. Enter the correct modes to perform the calculation and try again. ■Making Corrections During Calculations • If you make a mistake when inputting a value (but did not yet press an operator key), use Q to backspace and delete input digits one-by-one. Or you can press Q to clear the input entirely and start again. — 25 — • In a series of calculations, press Q while an intermediate result is displayed to clear only the last calculation performed. • To change the operator key (Q, B, B, B, W, AS, etc.) you just pressed, simply press the correct operator key. In this case, the operator of the last key you press is used, but the operation retains the order of precedence of the operation for the first key you pressed. ■Overflow or Error Check The following conditions make further calculation impossible. a. When a result (whether intermediate or final) or a total accumulated in memory is greater than ±9.999999999 x 1099. (“-E-” indicator appears on the display.) b. When function calculations are performed using a value that exceeds the input range. (“-E-” indicator appears on the display.) c. When an illogical operation (such as an attempt to calculate o and on while n — 0) is performed during statistical calculations. (“-E-” indicator appears on the display.) d. When an illegal mathematical operation (such as division by zero) is performed. (“-E-” indicator appears on display.) e. The total number of nested parentheses levels exceeds six, or when more than 18 pairs of parentheses are used. (“- H-” indicator appears on the display.) • To clear any of the above conditions, press T and perform the calculation from the beginning. — 26 — • In the case of condition e, you could also press Q. This clears the intermediate result just prior to the overflow, so you can continue with the calculation from that point. • No error occurs when the result is within the range of +(1 x10-99)to -(1 X10-19). Instead, the display shows all zeros. ■ Power Supply • fx-82SOLAR/fx-260SOLAR This calculator is powered by a solar cell that converts available light into electrical power. Solar Cell Precautions • The solar cell requires at least 50 lux of light to provide power. • If available light is too low, the display may become dim, calculation functions may become impossible, or the contents of the independent memory may be lost. If this happens, move to an area with more light. • fx-85B/fx-280 This calculator is powered by the CASIO TWO- WAY POWER system, which makes it possible for the calculator to operate even in total darkness. • The calculator retains memory contents no matter what the lighting conditions. • The TWO-WAY POWER system uses two power sources: a solar cell and a single G13 Type (SR44 or LR44) battery. • Weak battery power is indicated when memory contents spontaneously clear, or when the display darkens under poor light and cannot be restored by pressing M. — 27 — Important! Incorrect use of batteries can cause them to burst or leak, possibly damaging the calculator. • Be sure to replace the battery at least once every three years, regardless of how much the calculator is used. Old batteries may leak, causing serious damage to the interior of the calculator. • The battery that comes with the calculator when you purchase it is for testing only. It may not provide full service life. • Low bettery power can cause memory contents to become corrupted or lost completely. Always keep written records of all important data. • Always be sure to load the battery with its positive (+) side facing up (so you can see it). • Never try to charge batteries, take them apart, or allow them to become shorted. Keep batteries away from direct flame and heat. • Keep batteries out of the reach of small children. If swallowed, consult with your physician immediately. To replace the ba...
