What does half digit mean?
Digital meters are typically described as having “half digit” capability. A full digit is a display segment that can render all the numbers from 0-9, that is 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Half Digit. A half digit can display only the number 1. The half digit is always the first digit shown.
What is meant by the term 3 1 2 digit display?
A 3 1/2 digits meter can display 1999. A 4 1/2 digit meter can display 19999 and so on. The half means that the most significant digit can only go up to 1.

What is the range of 4 and half digit M?
The answer A 4.5 digit meter would be capable of displaying at least 20,000 counts (max value of 19999). It means you have four full digits and one half digit, only capable of displaying 1. The 4.75 digits is a more of a marketing term and could mean anything between 30,000 and 50,000 counts.
What does a 3.5 digit display mean in case of accuracy?
A 3.5 digit display displays numbers from 000 to 1999 or twice as much. By adding a relatively low cost display to the system the manufacturer doubles the displayed range. This results in eg multimeters with 2, 20, 200 Volt or mA ranges rather than 1, 10, 100, 1000 ranges.
Which is more accurate 4½ digit or 3½ digit DMM?
However, DMM accuracy also depends on other design factors, such as Analogue to Digital Converter (ADC) accuracy, component tolerances, noise level, and the stability of internal references. So, do not automatically assume that a 4½-digit meter is 10 times more accurate than a 3½-digit meter.
What can a four and half digit meter display?
By convention a half digit can display either a zero or 1. Thus a four and a half digit meter could display up to 19999. Occasionally a three quarters digit may be used instead of the half.
