20-7 Data Communications Precautions

Note the following precautions whenever you perform data communications.

• A TRANSMIT ERROR occurs whenever you try to send data to a receiving unit that is not yet standing by to receive data. When this happens, press A to clear the error and try again, after setting up the receiving unit to receive data.

• A RECEIVE ERROR occurs whenever the receiving unit does not receive any data approximately six minutes after it is set up to receive data. When this happens, press A to clear the error.

• A TRANSMIT ERROR or RECEIVE ERROR occurs during data communications if the cable becomes disconnected, if the parameters of the two units do not match, or if any other communications problem occurs. When this happens, press

A to clear the error and correct the problem before trying data communications again. If data communications are interrupted by A key operation or an error, any data successfully received up the interruption will be in the memory of the receiving unit.

• A MEMORY FULL occurs if the receiving unit memory becomes full during data communications. When this happens, press A to clear the error and delete unneeded data from the receiving unit to make room for the new data, and then try again.

• To send picture (graph) memory data, the receiving unit need 1-kbytes of memory for use as a work area in addition to the data being received.

Before using the Program Library

• Be sure to check how many bytes of unused memory is remaining before attempting to perform any programming.

• This Program Library is divided into two sections: a numeric calculation section and a graphics section. Programs in the numeric calculation section produce results only, while graphics programs use the entire display area for graphing. Also note that calculations within graphics programs do not use the multiplication sign

Description

Produces prime factors of arbitrary positive integers

For 1 < m < 10 10

Prime numbers are produced from the lowest value first. “END” is displayed at the end of the program.

(Overview) m is divided by 2 and by all successive odd numbers ( d = 3, 5, 7, 9, 11, 13, ....) to check for divisibility.

Where d is a prime factor, m i

= m i –1

/ d is assumed, and division is repeated until m i

+ 1 < d .

PROGRAM SHEET

Program for t -Test Value

No.

3

Description

The mean (sample mean) and sample standard deviation can be used to obtain a t -test value.

t =

( x – m ) x n – 1

n x : mean of x data x

σ n –1

: sample standard deviation of x data n : number of data items m : hypothetical population standard deviation (normally represented by

µ

, but m is used here because of variable name limitations)

Example To determine whether the population standard deviation for sample data 55, 54, 51,

55, 53, 53, 54, 52, is 53.

Perform a t -test with a level of significance of 5%.

Preparation and operation

• Store the program written on the next page.

• Execute the program as shown below.

Step Key operation Display Step Key operation Display

The above operation produces a t -test value of t (53) = 0.7533708035. According to the t -distribution table in the next page, a level of significance of 5% and a degree of freedom of 7 ( n – 1 = 8 – 1 = 7) produce a two-sided t -test value of approximately 2.365. Since the calculated t -test value is lower than the table value, the hypothesis that population mean m equals 53 is accepted.

Formula for circle: x 2 + y 2 = r 2

Formula for tangent line passing through point A ( x' , y' ): y – y' = m ( x – x' )

* m represents the slope of the tangent line

With this program, slope m and intercept b (= y' – mx' ) are obtained for lines drawn from point

A ( x' , y' ) and are tangent to a circle with a radius of r . The trace function is used to read out the coordinates at the points of tangency, and factor zoom is used to enlarge the graph.

Example

To determine m and b for the following values: r = 1 x' = 3 y' = 2

Notes

• The point plotted for A cannot be moved. Even if it is moved on the graph, the calculation is performed using the original value.

• An error (Ma ERROR) occurs when r = x' .

• Be sure to always perform a trace operation whenever you select trace and the message

TRACE is on the display.

Appendix B Power Supply

This unit is powered by four AAA-size (LR03 (AM4) or R03 (UM-4)) batteries. In addition, it uses a single CR2032 lithium battery as a back up power supply for the memory.

If the following message appears on the display, immediately stop using the calculator and replace batteries.

If you try to continue using the calculator, it will automatically switch power off, in order to protect memory contents. You will not be able to switch power back on until you replace batteries.

Be sure to replace the main batteries at least once every two years, no matter how much you use the calculator during that time.

Warning!

If you remove both the main power supply and the memory back up batteries at the same time, all memory contents will be erased. If you do remove both batteries, correctly reload them and then perform the reset operation.

k Replacing Batteries

Precautions:

Incorrectly using batteries can cause them to burst or leak, possibly damaging the interior of the unit. Note the following precautions:

• Be sure that the positive (+) and negative (–) poles of each battery are facing in the proper directions.

• Never mix batteries of different types.

• Never mix old batteries and new ones.

• Never leave dead batteries in the battery compartment.

• Remove the batteries if you do not plan to use the unit for long periods.

• Never try to recharge the batteries supplied with the unit.

• Do not expose batteries to direct heat, let them become shorted, or try to take them apart.

(Should a battery leak, clean out the battery compartment of the unit immediately, taking care to avoid letting the battery fluid come into direct contact with your skin.)
