What is a digital caliper?
|A digital (or electronic) caliper is a precision instrument used to take very accurate measurements.It is the most recent innovation in caliper technology.
|Measurements can be clearly read from the caliper’s LCD display.The LCD screen takes the place of the dial indicator of the dial caliper and the vernier scale of the vernier caliper, and makes the digital caliper much easier to use.
|Digital or electronic calipers are also able to take more accurate measurements.Most are able to measure up to 0.01 mm (0.0005 inches).
|Digital calipers can take measurements in both metric and imperial units, and some also allow fractional measurements to be taken.
The user can convert their measurements from one system to the other by pressing the mm/ inch button.
|The zero button enables the user to zero the caliper at any point.
This features makes calibration much more straight forward than with other types of caliper.
Taking comparative measurements is also easier. Simply measure the reference object, press zero then measure the object to be compared. The value displayed will be difference between the two dimensions.
|Some calipers can be connected to a computer.
This means that measurements can then be stored on a spreadsheet rather than recorded manually.
