OPERATING FUNDAMENTALS Power On/Off On/C Off To turn your calculator on, press [On/C]. To turn it off, press [Off]. If the calculator is already on, a single press of [On/C] clears the last entry; a double press clears all temporary values. If left on more than 12 minutes without activity, the auto–save feature shuts the calculator off, however, all memory values are preserved. Note: If the timer/stopwatch is running, the automatic shutdown is disabled.
Full Reset/All Clear + A/C Set Clears all values from memory and resets all settings to defaults. See Table 1 for a list of circumstances under which you may want to perform a full reset. Note: If you do not want to lose specific settings or values, have them written somewhere so you can re-enter them after a full reset. Battery Information GradeMatic 4000 is powered by a single 3-Volt Lithium CR-2032 battery. If the display becomes weak or erratic, replace the battery.

Cumulative Memory The GradeMatic 4000 has a cumulative Memory function that allows you to store a value for future use. When a value is stored in memory, it does not change until revised or the calculator is reset. Values can be stored in any format. You may also subtract and replace values. The following keys add, subtract and recall memory values: M+ Adds a displayed value to memory. Rcl M+ Displays the memory total. Set M+ Subtracts the displayed value from memory.

Grading Display The number “12” represents the number of grade entries, the value to its right is the numerical value of the last entry (defined by the grade format). To the right of the numerical value is the corresponding letter grade. All are identified by annunciators. (NUM, % and GRADE). “AVG” appears when averaging grades. “Error” & “None” Messages When an entry is incorrect or an answer is beyond the range of the calculator, the word “Error” will display.
GR A D I N G E X E R C I S E S To learn how to use GradeMatic 4000, we suggest that you carefully read and do the following exercises: Important! All exercises in this section use default values unless otherwise stated. Press [Set] [x] to restore GradeMatic 4000 to its default settings. Default Grading Scale The following examples use the default grading scale shown below.
Working with Maximum and Minimum Points Maximum Points Maximum Points is the highest score possible for a student to achieve on a given test or assignment as determined by the teacher. The default for maximum points is 100. Minimum Points Minimum points can either be set directly, or the GradeMatic 4000 can do this automatically. When set automatically, GradeMatic 4000 multiplies the maximum points by the D– breakpoint percentage (default is 60%).
Entering Maximum Points The following exercise shows how to change the maximum points and let the calculator figure the minimum points. You will also convert the following scores to percent and letter grades using a maximum points setting of 50. Student #1 Student #2 46 35 Step/Keystrokes Display 1. Clear calculator: [On/C] [On/C] 0. 2. Enter 50 maximum points: 50 [Max Pts] 50. 3. Find the minimum points: [Min Pts] 30. 4. Enter the student’s grades: 46 [# Grd] 35 [# Grd] 1 92.00 A– 2 70.
Entering Both Maximum and Minimum Points Using 150 maximum points and 80 minimum points, convert the following scores to percent and letter grades: Student #1 Student #2 130 93 Step/Keystrokes Display 1. Clear calculator: [On/C] [On/C] 0. 2. Enter 150 maximum points: 150 [Max Pts] 150. 3. Enter 80 minimum points: 80 [Min Pts] 80. 4. Enter the student’s grades: 130 [# Grd] 93 [# Grd] 1 86.66 B+ 2 62.
Resetting Maximum and Minimum Points to Defaults Step/Keystrokes Display 1. Return the maximum and minimum points to their defaults: [Off] [On/C] 0. 2. Verify the maximum points is 100: [Max Pts] 100. 3. Verify the maximum points for A+: [Max Pts] 100.0 A+ Note: To verify the entire table for maximum points, continue pressing [Max Pts]. 4. Verify the minimum points: [Min Pts] 60. 5. Verify the minimum points for A+: [Min Pts] 96.
Customizing GradeMatic 4000 With the GradeMatic 4000, you may customize your calculator to suit your special needs by: 1) Selecting the grade display format 2) Entering a custom grade scale. Preferences Before you begin grading, you may customize your calculator via the Preference function. Later you will learn to further customize your GradeMatic 4000 by setting a custom grade scale. The following keys are used to set preferences: Set Used to enter the Preference mode.
Settings & Defaults Note: The default option for each setting is identified with an asterisk (*). Scale Options: Defined below %* (True Percent) is the actual mathe- matical relationship between the maximum and actual points entered and the grade scale in use. For example, if the custom grade scales break point for D– is 60%, and the maximum/minimum points are set to 100 and 40, the D– break point displays as 40, not 60. PTS is used when grading on the Points system.
GPA 5 selects the GPA 5 format. Letter grades are scaled to the numerical equivalents of a 5.0 scale. For example, A is equivalent to 5.00, B to 4.00, etc. GPA 12 selects the GPA 12 format. Letter grades are scaled to the numerical equivalents of a 12.0 scale. For example, A is equivalent to 12.00, B to 9.00, etc. G% (Grade Scale Percent) correlates percentage to the custom grade scale.
Note: The default for each setting is identi fied with an asterisk (*). Set A–F Options: Set ALL Set A–F* To set break points for whole grades only, leave this setting at SET A–F. To set break points for + and – grades, select SET ALL. Note: Setting the A LL +, ALL – and A+ pref erences to OFF overrides this preference when SET A LL is selected. All + Options: On* Off If ALL + is set to OFF, plus grades cannot be entered or displayed. If a plus grade key is pressed, “None” displays. See SET A–F Note.
A+ Options: On* Off If set to ON, an A+ grade can be entered. If set to OFF, A+ cannot be entered or displayed. See SET A–F Note. Fail Options: F* E Depending on the option selected, a failing grade displays as an F or E. Beep Options: Off* On If set to ON, a beep sounds with each key press.
Review Maximum Points for Whole Grades Only This exercise requires you to temporarily change the ALL + and the ALL – preference settings to OFF. Step/Keystrokes Display 1.

Grade Weighting GradeMatic 4000 provides a grade weighting feature that can be used to weigh a grade more heavily than others. For example, the following table shows that homework and quizzes account for 50% of a student’s average, while the grade earned on his or her mid-term accounts for the remaining 50%.
dent earned an A– and you want it to have a weight factor of 5, you would enter: [A–] 5 [Wt]. Automatic Grade Weighting This method saves keystrokes and time by using the semi-permanent weight table. You can use this table to assign weight values for up to ten (10) grades. Once this table is set up, each grade entered is automatically weighted with the corresponding weight value.
Manually Weighted Letter Grades Enter and average these weighted letter grades using manual weighting: Grade # #1 (Homework) #2 (Quizzes) #3 (Mid-term) Grade Wt Factor B+ C– A– 1 (or 10%) 2 (or 20%) 7 (or 70%) Step/Keystrokes Display 1.

Custom Grade Scales With the GradeMatic 4000 you can enter, recall and store your own custom grade scale. Grade scales are usually set for whole-grade (A/B/C/D/F) break points with incremental breaks (B+/B/B–) automatically divided evenly within the whole-grade range. If preferred, you can manually enter your own values for the whole-grade and +/– break points. When entering a custom grade scale, the minimum value is used to define the minimum breakpoint of a letter grade.
Enter a Custom Grade Scale Sample Scale A = 93.0 – 100. C = 75.0 – 85.0 F = 0.0 – 65.0 B = 85.0 – 93.0 D = 65.0 – 75.0 Step/Keystrokes Display 1.
