What are digital instruments? 

Basically digital measuring instruments show the measured value in digital form which will be number along with its unit. And it is much easier to read compared to analog devices. One can easily measure and note the measured value by these digital devices as it will indicate the measured value in numerical form. They can give readings to one or more decimal places. There will be no human error in this type of equipment as it will show the value as calculated from the function. Hence the measured value will be more accurate as compared to analog instrument.
