描述 Description

The EMPCR200 is a single-chip LS1 CMOS calculator for 10-digit 1 memory or 12-digit 1 memory or 14-digits 1 memory, and up to 99 sets replay memory capacitywhich is useful for checking calculation process. Besides, the EMPCR200 is an arithmetic four standard types of general function (+,- , x, /), TAX function, Euro exchange, percentage calculation functions, leading zero and trailing zero suppression, chain calculations, MU calculation, Auto Power OFF available, 10/12/14-digit selectable LCD display. Dual power supply operation, wide operating voltage and lower power consumption make it suitable for 1.5 solar battery operated calculator.

特性 Features

Number of display:
10/12/14 digits of data, (including punctuation in each digit.) 1-digit of floating minus sign, memory load, error symbol, 3-digits of commas for thousands, TAX symbol,currency exchange symbol and 3 digits for replayfunction, \"CORRECT\", \"INS\", \"DEL\", \"%\", \"△%\", \"GT\",sing of four general functions (+, - , x, /), etc.., up to themin 18 symbols in 14 digit with replay function. Operation methods:
By algebraic operation.
Basic operations:
Four function, repeat multiplication and division, mixedcalculation, square calculation, percentage calculation,percent discount and add-on / discount calculation,memory calculation, delta percent calculation, add-modecalculation, mark-up / down calculation, Grand totalcalculation, constant calculation, tax calculation, EUROexchange, square root calculation, check, insert, andcorrect functions.
Decimal point method:
Decimal set lock key controls output format. Fixed decimal setting (\"0\", \"1\", \"2\", \"3\", \"4\", \"6\"), full floatingdecimal, and ADD mode (selectable with a switch).
Contents of operation:
1. Floating point mode during operation and key entrythat specified only Addition and Subtraction.
2. Specified decimal point mode is valid only foroperation results.
3. Round-off when most significant digits have higherpriority or at auto shift of rough estimation.
Key rollover method:
Two-key rollover
Error detect display:
1. Key entry exceeding the number of display digits isinvalid, but dies not cause an error.
2. If the integer part of an operation result exceeds thenumber of display digits, a rough estimate is displayed.
3. In the overflow condition, all key except \"C\",\"C/CE\", \"CE\", \"Δ\" key are inoperative.
Protection:
1. In the overflow condition, all key except \"C\",\"C/CE\", \"CE\", \"Δ\" key are inoperative.
2. Key chatter protection.
3. Auto-clear at power on
    Auto-clear functions by connecting a capacitor to the RESET pin.
Auto power off function:
1. 5 minutes
Clock source:
Oscillator / clock generator internal to chip.
Others:
1. Keyboard encoding internal to chip.
2. Wide supply voltage range (1.2 to 1.8V).
3. Very low power consumption.
4. Battery / solary power supply.
5. Symbol blinking available.
6. Rate will be kept after AC key pressed.
