Inputting Operations - Mitsubishi Electric MELDAS 600M Series Instruction Manual

1.4.2 Inputting operations

In addition to the method of directly inputting numeric data for specific data settings, a method to input the
operation results using four rules operators and function symbols can be used.
(1) Input method
Numeric values, function symbols, operators and parentheses ( ) are combined and set in the data
setting area.
The operation results appear when the
the data is processed and displayed on the screen. The contents in the data setting area are erased.

(4) Restrictions
• Always use "=" for the first character.
• Do not use the following characters as the second character or last character.
• Make sure that the left parentheses and right parentheses are balanced.
• The 360° limit does not apply on the angle. SIN (500) is interpreted as SIN (140).
