Calculator
The four-function calculator keys, + - x
, are available when you
are in any numeric data entry field. Just use these keys as you would any
calculator.
The keys will act on a number that is already in the field. For example, if you
move to a field which already has a value of 3.125, and you want to double it,
just press
x
ENTER
2 to get 6.250.
When you have more than one calculation in a field, the calculator will
perform multiplication and division before it does addition and subtraction.
This means that you can enter
+ 3 1 8 to get three and one-
eighth (the 1 ÷ 8 is done before the 3 is added).
The VRO 300M can calculate trig functions, tilt angles, and rotational speeds.
Press the
CALC
key, and the following softkeys appear.
Trig Functions
When you’re entering data for a position function, you may need to calculate
dimensions using the trig calculator. Press the
TRIG
softkey, and the
following function softkeys are shown.
Most of the calculator softkeys are divided in half. At first, the top half is
“active”, while the bottom half is “inactive”. Press the
SHIFT
softkey and the
bottom half of the calculator options becomes active.
Typically, a result is calculated by entering a number and then selecting the
appropriate math function. For example, to enter a number whose value is
the square root of 2, press
