I Logical Operators (AND, OR, NOT, XOR)
[OPTN]-[LOGIC]
The logical operator menu provides a selection of logical operators.
• {And}/{Or}/{Not}/{Xor} ... {logical AND}/{logical OR}/{logical NOT}/{logical XOR}
• Be sure to specify Comp for Mode in the Setup screen.
Example What is the logical AND of A and B when A = 3 and B = 2?
A AND B = 1
