The connection for the test leads is Black lead to the + terminal and Red lead to the - terminal.

The connection for the test leads is Black lead to the + terminal and Red lead to the - terminal.

• A. True
• B. False
• C. Not specified
• D. Depends on model

Answer: (B)

In electrical testing, red is used for the positive connection and black for negative/common. This convention keeps DC readings meaningful and sign-consistent. Swapping them by connecting the black lead to the + terminal and the red lead to the - terminal reverses the polarity, which usually yields a negative reading or an inverted result, leading to confusion or errors. While AC measurements don’t rely on polarity, for DC the standard red-to-plus, black-to-minus is what you should follow. Therefore, the statement is not correct.
