elapsed from the start of the timer to the moment the [S/Lap] key is pressed will be displayed. If set to the “Lap” option, the elapsed time between presses of [S/Lap] is displayed. Other Function Keys [Prefs] — Preference Settings A multi–press key used to access and change the default preferences. Once in the preference setting mode, the [+] and [–] keys are used to change preference options. [Conv] [#] — Inverse Function Calculates the inverse of the displayed value.
[Rcl] [=] — Paperless Tape Used to verify the last entries or operations of a calculation. See “Paperless Tape.” [Conv] [Rcl] — Clear Memory “0” Clears the value in the cumulative memory cell “0” without changing the display.
OPERATING BASICS Basic Math Your calculator uses standard chaining logic, which simply means that the calculations are made in the order entered. 3 [+] 2 [=] 5 3 [–] 2 [=] 1 3 [x] 2 [=] 6 3 [÷] 2 [=] 1.5 Percent Calculations The percent [%] key is used for finding a given percentage of a number or for working add–on, discount or division percentage calculations. 355 [x] 15 [%] 53.25 250 [+] 6.5 [%] 266.25 25 5 [%] 50 [%] [–] 100 [÷] 23.75 200.
Delta Percent The Delta Percent function finds the percent change between two values. The [=] key must be pressed to complete the calculation. 10 [Conv] [%] 15 [=] 50. 100 [Conv] [%] 25 [=] – 75. Memory Functions The Time Master II can store and recall up to 10 separate 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. Function Keystrokes Store value in mem. [Stor] [0] ...
Memory “0” Storage register “0” 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): Function Keystrokes Subtract from mem. “0” [Conv] [Stor] [0] Display/Clear mem. “0” [Rcl] [Rcl] Clear mem. “0” without changing the display [Conv] [Rcl] Using Memory “0” Keystrokes 355 [Stor] 0 255 [Stor] 0 [Rcl] 0 745 [Conv] [Stor] 0 [Rcl] [Rcl] Display 355. M–0 255. M–0 610. M–0 745. – 135.
Preference Function The Time Master II includes a special preference function that allows you to customize the calculator for your specific needs or special situations. To access the preference function, simply press the [Prefs] key. Repeated presses of this key will scroll through the various options which may be altered by pressing [+] or [–] keys. 1– Seconds (On / Off) 2– Rate Display 3– • 0.00 • 0. • 0.0000000 Timer Format • 0:00:00.0 • 0:00:00.

Preference settings will not change until revised or the calculator is reset.
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 = Error Point x Period = Error Point x Point = Error Period x Number = Period 9 Hrs. X 3 = 27 HR Point x Number = Error Division Period # Period = Number 9 Hrs. # 9 Min. = 60 (9 min. segments) Period # Number = Period 9 Hrs.
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 [Mode] key to toggle between formats, you can choose to enter time in decimal format (default), auto entry H:M:S format, or auto entry 24–hour format. Keystrokes [Mode] [Mode] [Mode] Display AUTO 0:00:00 HR MIN SEC AUTO 00:00:00 0. DEC Decimal Format 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 [AM] or [PM]. Steps Clear calculator Enter 8:05 AM Keystrokes [On/C] 805 [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. H:M:S formatted values are limited to less than 100 hours.
Auto Entry 24–hour 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 calculator is in a cleared state. 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 zero or 00:00:00 after every 24 hours.
Time Conversions One of the most useful functions of the Time Master II is its ability to convert between all time formats with the touch of just two keys: [Conv] and [the time format you desire]. To illustrate: 1. Enter 3 hours, and 30 minutes into the calculator as follows: 3 [Hr] 30 [Min] 2. Now convert this to other formats: [Conv] [Conv] [Conv] [Conv] [Hr] [Min] [Min] [Sec] 3.

Beginning, End & Duration The [Beg], [End] and [Dur] 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 [Beg] and [End] registers. Only periods of time can be entered into [Dur]. AM/PM entries for duration cause an error.

[Rcl] [Rcl] ANSWER: 2:39:00 HR MIN SEC 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. You can have the display count in whole seconds, one decimal place, or two decimal places by setting the timer preference (using the [Prefs] key).
Storing Time Values Values obtained from the timer can be stored or used in calculations. Steps Keystrokes Clear calculator [On/C] [On/C] Start timer [Timer] [Timer] Freeze timer display [S/Lap] Enter value into memory [=] [Stor] [1] Recall memory [On/C] [Rcl] [1] Calculating with Time Values 1.
