OPERATING BASICS Basic Math Your calculator uses standard chaining logic, which simply means that the calculations are made in the order entered. Keystroke Display 3+2= 5 3–2= 1 3x2= 6 3÷2= 1.5 Percent Calculations The percent % ] key is used for finding a given % of a number or for working add-on, discount or division % calculations. Keystroke Display 355x15% 53.25 250+65% 412.5 25–5% 23.75 100÷50% 200. Delta % The function finds the % change between two values.
Cumulative Memory (M+) s 0 (M+) is a cumulative memory in which values of the same convention can be added. It has the following special keystrokes (in addition to those defined above): Steps Subtract from M+ Display and Clear M+ Clear M+ without changing the display Keystroke Cs0 rr Cr Using M+ Keystroke 355s0 255s0 r0 745Cs0 rr Display M+ 355. M+ 255. M+ 610. ‘ ‘ ‘ ‘ M+ 745. - - -135.
Memory Functions The Time Master™II can store and recall up to 9 separate non-cumulative Memory values. When a value is stored in Memory, that value does not change until it is revised or the calculator is reset. Values can be stored in any format. Steps Keystroke Store value in Memory s 1 ... 9 Recall value in Memory r 1 ... 9 Clear one Memory value 0 s 1 ...9 Clear all Memory values C+ Storing Values Keystroke 355s1 o r1 25s1 o - r1 0s1 10 — Time Master II Display M-1 355. 0. M-1 355. ‘ ‘ ‘ ‘ M-1 25. 0.
Preference Settings The Time Master™II includes userselectable preference settings that allow you to customize the calculator for your specific needs or special situations. To access the preference settings, simply press the P key. Repeated presses of this key will scroll through the various options which may be altered by pressing + or – keys.
Time Conventions When you are dealing with time, there are actually two kinds of time values that must be considered: 1. Points in Time: 9:22 AM, 5 PM 2. Time Periods: 37 Minutes, 45 Seconds The time math rules are as follows: Addition Period + Period = Period 3 Hrs. + 22 Min. = 3 HR 22 MIN Point + Period = Point 9 AM + 22 Min. = 9:22 AM Point + Point = Error Note: You cannot add two points in time as the result would be meaningless. Subtraction Period – Period = Period 3 Hrs. – 22 Min.
Multiplication Period x Period Point x Period Point x Point Period x Number 9 Hrs. X 3 Point x Number = = = = = = Error Error Error Period 27 HR Error Division Period ÷ Period 9 Hrs. ÷ 9 Min. Period ÷ Number 9 Hrs. ÷ 60 Period ÷ Point Point ÷ Period Point ÷ Number Point ÷ Point = = = = = = = = Number 60 (9 min.
USING THE TIME MASTER™ II ENTERING TIME VALUES The Time Master™II allows the user to enter time in several different ways. By using the M ] key to toggle between modes, you can choose to enter time in Decimal format (default), Auto-Entry H:M:S mode, or Auto-Entry 24-hour mode. Keystroke Display AUTO M 0:00:00 HR MIN SEC AUTO M 00:00:00 M DEC 0. Decimal Mode In this mode entries are made for regular or time calculations (when defined with the time unit keys).
If you are entering points in time, you do not have to use the : key. Under this method you would enter the time as it is read, then press A or p. Keystroke Display Enter 8:05 am in Decimal mode: 805A 8:05:00 AM Auto Entry H:M:S Mode In this mode, the calculator assumes the value is being entered in an Hour: Minute:Second (H:M:S) format. The calculator will scroll the numbers entered from right to left. Entered H:M:S formatted values are limited to less than 100 hours.
Auto Entry 24-hour Mode This mode is used to automatically enter time in a 24-hour format. It will display a 00:00:00 without the HR MIN SEC identifiers when the display is cleared. Time in this mode is entered in the same way it is in the H:M:S mode, but the time values will roll back to 00:00:00 after every 24 hours.
Time Math Simple Addition Keystroke Display Add the following time values: 112H+ 112:00:00 HR MIN SEC 3 3 m 2 2 ß + 112:33:22 HR MIN SEC 3H21m+ 115:54:22 HR MIN SEC 145ß+ 115:56:47 HR MIN SEC 1 7 m 1 2 ß + 116:13:59 HR MIN SEC 33•75m 33:75 MIN = 116:47:44 HR MIN SEC Athletics – Split Times Required A marathon runner wants to run a 26.2 mile marathon in 3 hrs 15 min. How fast should he run each mile? Keystroke Display Enter total time: 3H15m 3:15: HR MIN Divide by miles: ÷26•2= 0:07:26.

How long will it take to process 1,250 forms? Keystroke Enter Time 10m Divide by number of forms: ÷17= Display 10: MIN SEC 0:35.29 MIN SEC Multiply by 1250: x1250= 735:17.65 MIN SEC Convert to H:M:S: format: CH 12:15:17.
Keystroke Display Enter end time: 10A Subtract start time: 10:00:00 AM –6A= 4:00:00 HR MIN SEC Divide by number of spots: ÷15= 0:16:00 HR MIN SEC Store result into memory: s1 M-1 0:16:00 HR MIN SEC Enter start time of 1st spot: 6A 6:00:00 AM Find start time of 2nd spot: +r1= 6:16:00 AM Find start time of 3rd spot: = = 6:32:00 AM 6:48:00 AM Continue pressing = to solve for the remaining spot start times.
Beginning, End and Duration The B, E and D keys are used to calculate starting and ending times as well as duration of time. Given two values, the third can be easily found. You may enter a whole number, a point in time or a period of time into the B and E keys. Only periods of time can be entered into D. AM/PM entries for duration cause an error. Scheduling – Multiple Steps A delivery truck travels 132 miles from Los Angeles to Palm Springs.

Using the Timer The Time Master™II includes a full function stopwatch / timer with buzzer and split / lap functions. The timer can count up from zero or count down from an entered time. The display counts in whole seconds, one decimal place, or two decimal places by setting the timer preference (using the P key). Press the O key while the timer is running and the timer will be displayed. The calculator will beep to let you know the timer is still active.
Storing Time Values Keystroke Display Access and start timer: T T TMR GO 0:00:00.0 HR MIN SEC 0:00:01.6 HR MIN SEC Freeze timer display: S s1 0:00:05.1 HR MIN SEC 0:00:05.1 HR MIN SEC Clear display and recall value in Memory: o 0. M-1 r1 0:00:05.1 HR MIN SEC Exit timer and clear display: TToo 0. SPLT M-1 The example below uses the value stored in the previous example. If you have not already done that example, go back and complete it before performing the next example.
Split / Lap Function You can select whether the S key acts like a split function or a lap function through the preference settings. Set to the SPLIT function (default). When you press the S key, the calculator will pause the timer display, and show the amount of time elapsed from the start of the timer to the time the key was pressed. The second press returns to the counter, the third press stops it again, etc. Set to the LAP function and press the S key.
PAPERLESS TAPE FEATURE The “Paperless Tape” feature allows the user to display the last twenty entries. While in the Paperless Tape mode, the display will look similar to this: A = Sequential number of entry (01–1st entry, 02–2nd entry, etc.
How to use the tape Keystroke Display Clear calculator and enter a string of numbers: oo 0.
Clearing the Paperless Tape: The Paperless Tape is cleared upon: 1) a double press of o; 2) a Clear All ( C x ); 3) the start of a new string of equations after exiting the tape function (starting with a number, not an operator); or 4) turning the unit off. Rate Function The rate function is used to multiply a numerical or time value by a per-unit rate. This is primarily used for finding costs based on a per-unit time price structure.
Billing A consultant who bills at a rate of $125 per hour reports the following hours: • 2 Hrs 20 Min • 1 Hr 15 Min • 35 Min • 4 Hr 35 Min Find the total hours and total bill, using a temporary rate value. Keystroke Display Enter 1st value: 2H20m+ 2:20:00 HR MIN SEC Add 2nd value: 35m+ 2:55:00 HR MIN SEC Add 3rd value: 1H15m+ 4:10:00 HR MIN SEC Add 4th value: 4H35m= 8:45:00 HR MIN SEC Multiply by rate: x125R RATE 1093.75 Scheduling – Assembly An assembly line can produce 4.
Scheduling – Payroll Your part–time office assistant’s time card reads as follows: Day In Out Monday 3:30 PM 5:30 PM Tuesday 3:15 PM 7:00 PM Wednesday 3:30 PM 4:45 PM If he earns $6.
APPENDIX ADDITIONAL INFORMATION Accuracy/Display – Your calculator has an eight digit display. In a standard calculation, each calculation is carried out internally to ten digits and is rounded to an eight digit value. A 5/4 rounding technique is used to add one to the least significant digit in the display if the next non-displayed digit is five or more. If this digit is less than five, no rounding occurs.
WARNING Because the batteries contain hazardous chemicals, please use caution when disposing of old batteries. Keep them away from animals and young children. Automatic Shutdown – The calculator is designed to shut itself off after eight to ten minutes of inactivity. Values shown on the display will be cleared. Note: If the timer/stopwatch is running, the automatic shutdown will occur after eight hours.
