Calc Hard key
ND 522/523’s calculator is capable of handling everything from simple
arithmetic to complex trigonometry, and RPM calculations.
Press the CALC hard key to access the STANDARD/TRIG, and RPM
soft keys.
Trig functions contain all trig operators as well as, square, and square
root. When calculating the SIN, COS, or TAN of an angle, enter the
angle first, and then press the appropriate soft key.
When more than one calculation is entered into a numeric
field, the calculator will perform multiplication, and division
before it performs addition, and subtraction. If this were to
be entered: 3 + 1 ÷ 8, ND 522/523 will divide one by eight,
then add three for an answer of 3.125.
Angle values use the current angle format selection of
decimal degrees, or radians.
