Configulator Help
[Updated 23 Jan 2015]
Configulator
Calculator is a scientific calculator with 16 keys [F0-F15] which can be
configured[Programmed]. This allows the
user to define functions that are relevant to them, not what the calculator
designer has decided.
Most
in-built features follow standard operation and are therefore intuitive; the
features that may not be intuitive are described below.
Exponents
To enter a number with an exponent, press EXP then enter the
exponent using the number and +/- keys.
Percentage Calculations
Percentage
calculations are as shown below:
7.35 % 5 + 7
Adds 5% to the display value
10 % 8.1 - 9
Reduces display value
by 10%
20 15 % * 3,
Returns 15% of value to the display
16 % / 8 50
Returns the value of the division as a percentage
Power and Root Functions
There is no specific Square Root or Square keys, the Xn and
n√X by default perform these functions.
To obtain other power and root functions the second parameter is
entered.
EG
Square Root
n√ = 3 9
Returns
the sqrt. of value to the display
Cubed
Root
n√n 3 = 2 8
Returns
the cubed root of value to the display
Squared
Xn = 81 9
Returns
the value squared of value to the display
Cubed
Xn 3 = 8 2
Returns
the value cubed of value to the display
The
default square and square root functions are now activated by the =+-/*)
IE (3 Xn + 4 Xn) n√=5
Random Numbers
The RND# key generates random numbers in two modes
With value 0 displayed the RND# key generates a random decimal
between 0 and 1 inclusive.
0 RND# 0.14159265 ,
With an integer [N] displayed, the RND# key generates a random
integer between 0 and [N] inclusive.
100 RND# 67 ,
In both cases if the original displayed value is not an integer
it will be rounded to the closest integer before the random number is
generated.
Round Numbers
The Round key gives the option to round the displayed number
using normal rounding rules or to “truncate the number to a specified number of
decimal places.
The user enters the number for decimal places after the operation of the Rounding/Truncate
key. The user input is always converted
to a positive integer.
DRG Key
The DRG key cycles the calculator through modes of angles. Degrees, Radians and Grads. The DRG key only changes the calculator mode
not the current value displayed.
EG If the calculator is
in the default mode of Degrees with 45 displayed changing the mode to Radians
means the calculator will interpret this as 45 Radians.
DRG> Key [Shift DRG]
The DRG> key cycles the calculator through modes of
angles. Degrees, Radians and Grads.
The DRG> key also converts the current value display.
EG If the calculator is
in the default mode of Degrees with 45 displayed changing the mode to Radians
means the calculator will change this to 0785398 Radians.
Hyp Key
The Hyp key activates the Hyperbolic Trig functions. These functions only operate for Radians
The default for Hyp is that it latches in to Hyperbolic mode
until the Hyp key is operated. The
Settings menu allows the user to set this to non-latching
and the calculator reverts to normal mode after each Hyperbolic
operation.
FFSE Key [Previously DFSE]
The FFSE key cycles through modes of number display. Float, Fixed decimal places, Scientific and
Engineering modes.
NDP
Key
The NDP Key is used to define the number of decimal places
displayed.
For Float, Scientific and Engineering modes this is the
“Maximum” number of places.
For “Fixed” that number of decimal places is always displayed.
FFSE Shift 5
EG
Sets the number of decimal places to 5.
ABS Key
The ABS key toggles the calculator in and out of “Absolute”
mode. This mode return all results as absolutes.
EG 3 - 11 = |8|
HIST Key
This key shows recent calculated results [Max 20].
MENU
The Menu can be accessed via the device menu key or “Shift” “AC”
on the calculator key board
Settings available are Vibrate On/Off, Click On/Off, Hyp Latch
On/Off and “Keep Screen On” to stop screen automatically blanking.
PGM Key
This key takes the user in to Programing mode to define the
functions of keys F0-F15.
Full details of programming are below.
Rslt Key
Rslt key shows the result/s of the most recent F0-F15 operation.
Programming Keys F0-F15
The programming in the Configulator is basically a key stroke
recorder.
As a key stroke recorder there is virtually no capacity for
editing, so the user should carefully plan the actions before starting.
- When the PMG key is operated the
user is first requested to select which key to assign.
- The user is then requested to enter
the “name” for the function via the virtual keyboard. This “name” will replace the default Fx
label. The name has a maximum of 5
characters.
- The user is then requested to enter
the “name” for the result via the virtual keyboard. The name has a maximum of 15
characters. [Does not need to be
the same as the function name.]
- After the result name is entered
the calculator keyboard is displayed with a changed format. Some keys are blanked as their functions
are not available during programming and 3 memory keys have new functions.
Ø
VAR key is used to initiate the entry of a variable name. EG X, Y Etc.
Ø
NEXT key is used to complete one formula and commence the next
formula in the same function.
Ø
DONE key ends the programming sequence.
- After the DONE key is operated the
calculator returns to normal function with the new name displayed in place
of the default Fx label.
NOTE: To delete a program and return the Fx key to the default;
commence the programming sequence and at step 2 leave the name blank and click
the DONE key.
Examples:
Assign a Constant: Assign
the “Golden Number” to F0 [1.6180339887499]
Programming sequence:
1.6180339887499 ENTER GoldN DONE ENTER PGM F0 GoldN
Select PGM, select F0, enter GoldN as label name, enter GoldN as
result name, enter the number and click the done key.
F0 will now be displayed as “GoldN” and Shift-Zero will enter
the Golden Number in the display.
Assign a Formula: Assign the
formula for circumference of a circle to F1
[C=2∏r]
Programming sequence:
= * VAR r DONE = ENTER 2 * ∏ F1 Circ ENTER Circumf ENTER PGM
When Shift-One is operated the user will be
requested to enter a value for “r”. The
equals key becomes the ENTER key.
The result will be the circumference of a
circle for radius “r”
Assign two Formula: [nPr(n,r)
= n! / (n-r)!] [nCr(n,r) = nPr(n,r) / r!]
nCr and nPr are functions commonly found on calculators,
with Configulator both functions
can be
assigned to one key and calculated simultaneously.
Programming sequence:
/ = n! ENTER n ENTER nPr VAR ENTER nXr F4 PGM
- ENTER VAR r n! NEXT ) = n VAR ENTER ( Cont.
.
DONE = n! ENTER r VAR / ANS ENTER nCr Cont.
.
When Shift-Four is operated the user will be
requested to enter 2 inputs
[n,r] and 2 outputs will result:
[nCr,
nPr].
Definition:
nCr the number of different, unordered combinations of r objects from a
set of n objects.
Definition:
nPr the number of possibilities for choosing an ordered set of r objects from a
total of n objects.
Antenna Return Loss: RLoss = 10LogP1/P2
Programming sequence:
ARL F5 PGM ENTER RLoss
db ENTER
Cont.. ABS ENTER Fwd
Power VAR / = Ref
Power ENTER VAR
DONE Log = 10 * = ABS Cont..
