logic, which simply means that the
calculations are made in the order
entered.

given % of a number or for working
add-on, discount or division
% calculations.

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.
User’s Guide — 13
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

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

Decimal Mode
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
as they are spoken aloud, with the
largest time unit entered first.
Keystroke Display
Add the following time values in Decimal mode:

* If you are not in Decimal mode,
repeatedly press M until DEC 0. is
displayed.
User’s Guide — 15
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. However, the calculator will display results greater than
100 hours in H:M:S format.

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 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:cCand any of the
time unit keys: H m or ß.

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 — 27
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. You may clear the value by
performing a “Clear All” (C x) or
replace it with another value.
Entering a unitless value, then pressing
s R will permanently store that
value as the rate. When entering a
math string, R pressed after a unitless value will override the previous
rate. For example, if you enter
2 • 5
H x 1 0 R
TimeMaster II
uses
10 as the rate instead of the stored
value.
Note: Trying to enter a time value into
the rate key causes an error.

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.
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 o 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.
Clear All – Your calculator is equipped
with a special two-key sequence, C x
to clear all Memory 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 (one year
plus for most people). Should the display become very dim or erratic, replace
the battery.

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.
