Why when I press CE to clear a number is it still saved, how can I truly zero out the numbers?

I think this has been answered very fully by Dazzy B - his answer is below :-

The zero capture is out of the 2percent tolerance so the cell is either faulty or requires zeroing. Open the unit and press and hold the micro switch on the left of the board. The display flashes s. Press the zero key to change to flashing E. Press store to scroll to zero balance. Press semi auto tare. This captures zero without clearing the span calibration. The display will scroll around for a short period when complete press store.. Release the micro switch and scale will go thru warm up routine then display zero. Hope this helps, regs Darren.

Hi Steven:
You should be able to key in the number, then press (memory plus).
After that, press (clear) once. That should leave the number in memory but leave the display at zeroes.
- 1) Then you would enter your number, Press (divide) symbol, then press (memory recall), then press (equals).
The answer should display. Press (clear) once. resets to zero
- Repeat (1) as above for next numbers.
Hope this helps.
Cheers.

Clear the LCD screen to zero
To multiply numbers, enter the first number by typing the number key pad; press the "X" key and enter the next number; to tabulate those two numbers, press the "=" key

For example, if you want to multiply the two numbers 125 by 425, the expression pressed on the calculator would be 125 X 425 =

CE stands for Clear Entry. It clears the number that one just entered. To clear the results of a previous calculation use the key AC, if calculator has one. Otherwise try pressing the CE key twice or enter 0, because that is what the clear button will do.

Hi, here are some of the answers to your questions.

GT:- Grand Total: It shows the cumulative total of your calculations

MU:- Mark Up: It is used to calculate the CROSS PROFIT MARGIN in business environment.

MRC:- If pressed once, it shows the number stored in the memory. If pressed twice it clears the memory.

AC:- All Clear: It clears everything

CE:- Clear Entry: Clears the last entry of calculations.

ON/C: If the calculator is off, it turns it on. If the calculator is on it clears all entries.

If you have any more questions you can visit this site: http://www.aurora-ltd.co.uk/OpInst/FunctionsGuide.htm it has almost everything covering the calculator buttons.

To set the calender: Press the Calender/Time button. Press and hold the Time Set button for 3 seconds; the first digit of the date will start blinking. Then type in the date as two digit number for the month and date and a 4 digit number for the year. Add a zero in front of the month or day if under 10. Then press Time Set again. Press the CE/C button to return to the Calculation mode
(hold for 3 seconds)
Thus for today [Cal/Time] [Time Set] 0 9 1 5 2 0 1 0 [Time Set] [CE/C]

(hold for 3 seconds)
For December 1, 2010 [Cal/Time] [Time Set] 1 2 0 1 2 0 1 0 [Time Set] [CE/C]

To set the Time from the Calculator mode, you press the Calender/Time button twice before pressing and holding the Time Set button for 3 seconds; again the first digit of the current time will blink. Then type in the time as a 4 digit number followed by the AM/PM button to switch from AM to PM or PM to AM. Then press the Time Set button again and then the CE/C button to return to the calculator mode. You will see an A (AM) or P (PM) to the right of the time as you set it.

So for 5:06 PM you type
(hold for 3 seconds)
[Cal/Time] [Cal/Time] [Time Set] 0 5 0 6 [AM/PM] [Time Set] [CE/C]

I hope this helps. You can find the manual here: http://www.usa.canon.com/cusa/consumer/products/calculators/printing_calculators/mp11dx#BrochuresAndManuals as a pdf.

(I'm using Cal/Time for the button that has an icon that looks like a 1 month calender on the left and a clock on the left.)

Programming a frequency into a channel clears the previous channel entry, so there's really no need to "clear" the scanner for reprogramming. To eliminate an unwanted frequency, you can either press the LOCKOUT key to prevent the scanner from stopping on a specific channel, or you can "zero" a channel:

1. Press SCAN/MAN to stop
scanning.
2. Use the number keys to enter
the channel number (1-200)
you want to clear.
3. Press PGM. F=C appears.
4. Press 0 then ENT. The
frequency number changes to
000.0000 to indicate the
channel is cleared.

Press the Date and Time button, when you see the date on the display screen, then press = and hold, you will see the first number blinking, then just type in the numbers (day - month - year) it moves along as you type, when you are done, press = for 1 sec the date is now set. Now to set the time press the Date and Time button again, you will see the time showing on the display, press and hold = until the firs number starts blinking, then proceed to type in the time, when you are done, press = for 1 sec the numbers are supposed to stop blinking. the date and time is set, then clear your screen (press CE/C) the date and time are saved.

Yeah, this calculator is kind of odd in that the keys to the left of the numbers ([÷], [×] and [=]) work more like standard calculators, but the keys to the right ([-] and [+]) work more like they're RPN (more common on HP calculators). To calculate 1000-490, type "[CE/C] 1000 [+] 490 [-]". What happens is this: after clearing then entering 1000, the [+]adds it to the last result (in this case 0), giving us 1000. This number is saved when you enter 490, and pressing [-] subtracts it from the last result (1000), giving you 510.
