Basic functions
The Arc and Bolt Pattern features are not supported by the zoom in/out
feature.
Calculator
You use the Calculator function to do basic and trigonometric calculations.
The current axis positions are displayed in calculator mode to save you
having to remember these values if you need them for your calculations.
The Calculator display screen clearly shows the calculations performed.
The following screen is displayed when you press
in Normal mode.
As shown on the screen, the big square on the LCD contains all the
results and the small rectangle is for the present number entry. The results
are displayed when you press the [
enter
] key.
The following operators are available:
Math Functions.
(+, -, ×, ÷, %). These operations are performed on two
operands. The following sequence illustrates the method of operation.
If you want 23.596 × 131.567 then you should follow this sequence:
[
2
] [
3
] [
.
] [
5
] [
9
] [
6
] {
×
} [
1
] [

] [
1
] [
.
] [
5
] [
6
] [
7
] [
enter
]
The result displayed is '3104.4549'. You can use this result for other
operations.
Trigonometric Functions.
(sin, cos, tan, sin
-1
, cos
-1
and tan
-1
).
These operate on a single operand. This operates on the number in the
entry field. The result is displayed in the entry field, replacing the original
number that you entered. You can perform other operations on this result.
The trigonometric functions consider the operands in degrees and not in
radians.
If you want sin (43.14) then you should follow this sequence:
[
4
] [
3
] [
.
] [
1
] [
4
] {
sin
}
The result displayed is '0.6837833'.
Other Functions.
(1/x, x
2
, x
y
, etc). These operate on a single operand
except for xy which operates on two operands similar to the Math
functions.
In addition to the above functions, you can use brackets to help order the
functions. The following example shows how to use the brackets:
If you want 143 + sin (180/23.5) then you should follow this sequence:
[
1
] [
4
] [
3
] {
+
} {
(
} [
1
] [
8
] [
0
] {

} [

] [

] [
.
] [
5
] {
)
} {
sin
} [
enter
]
The result displayed is '143.13328'.
You can use the value of
π
in the calculations using the symbol.
You can use the number in the entry field to load a particular axis during
any operations. You need to press the axis key to load the axis.
To exit the Calculator function, press the slider bar close to the
