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. = 2 HR 38 MIN
Point – Period = Point
9 AM – 22 Min. = 8:38 AM
Point – Point = Period
9 AM – 8:30 AM = 30 MIN
Period – Point = Error
Note: When subtracting one point in time
from another, it’s best to enter the “later”
time first, then subtract the earlier time.
14 – Time Master™II
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. # 60 = 9
MIN
Period # Point = Error
Point # Period = Error
Point # Number = Error
Point # Point = Error
User’s Guide – 15
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.

In this mode entries are made for regular or time calculations (when defined
with the time unit keys). Time values
are entered into the calculator pretty
much as they are spoken aloud, with
the largest time unit entered first.

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

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

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).
If you press the [Off] key while the timer
is running, the timer will display and the
calculator will beep to let you know the
timer is still active. The second press of
the [Off] key will shut off the calculator.
1. To count up from zero press:
[Timer] [Timer]
2. To count down, enter the time from
which you want to count down while
the timer is displayed:
[Timer] 110000 [Timer]
While the timer is counting, you will see
the clock symbol flashing on the bottom
left of the display. The star symbol will
also appear if the timer buzzer is on.

Note:
To exit the tape mode, you can press
a
ny key besides [Off], [+] or [–].
When you press a key to exit the tape, the
calculator will display the last value
entered into the tape. If the value was [=]
the display will show the total (TTL =). If
there were more than one [=] during the
string, the last [=] pressed will show as the
total, and all others will be designated as
subtotals (SUB =). The next press will
begin a new tape function.
User’s Guide – 29
Clearing the Paperless Tape:
The paperless tape is cleared upon:
1) a double press of [On/C];
2) an All Clear ([Conv] [x]);
3) the start of a new string of equations
after exiting the tape function (starting
with a number, not an operator); or
4) when you turn the unit off.
Rate Function
The rate function (accessed by pressing
[Rate]) allows you to multiply a dimen-
sion by a number (rate) to get an output
that is a unitless number rather than a
dimensional value. This is primarily used
for finding costs based on a per unit
time price structure.
Entering a unitless value before pressing the [Rate] key will permanently
store that value as the rate, unless [Rate]
is used to terminate an equation ( i.e.,
1[Hr] [x] 25 [Rate]).
If [Rate] is used to terminate a multiplication string, the value entered prior to
[Rate] will temporarily override the per-
manently stored rate.
Note: Trying to enter a time value into the rate
register causes an error.

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 a 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.
Errors — When you make an incorrect
entry, or the answer is beyond the
range of the calculator, it will display
the word “Error.” To clear an error condition you must hit the [On/C] button.
At this point you must determine what
caused the error and rekey the problem. An error will also occur if you
enter a mathematical impossibility such
as division by zero.
Full Reset/All Clear — Your calculator is
equipped with a special two-key
sequence, [Conv] [x] to clear all memo-
ry registers to their default values.
Battery Information — Your calculator is
powered by a single 3-Volt Lithium CR-

2032 battery. This should last upwards
of 800 hours of actual use (1 year plus
for most people). Should the display
become very dim or erratic, replace the

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 is disabled.
