What is the difference between three and a half digits and four and a half digits of a digital multimeter?
Answer: The three and a half digits are also called 3 1/2 digits (pronounced as three and a half digits), and the four and a half digits are also called 4 1/2 (pronounced as four and a half digits). We know that after an analog quantity is quantized and converted into a number, the precision represented by it is related to the number of digits of the number. The more digits, the closer to the original value, the more accurate (this is generally speaking , regardless of other circumstances, if the quantized value is 1.00000V, the one-bit representation is the same as the N-bit representation (:). So in general, the more digits, the more accurate, that is, four digits Half is more accurate than three and a half.
