The Digital Caliper (sometimes incorrectly called the
Digital Vernier Caliper) is a precision instrument that can be used to
measure internal and external distances extremely accurately. The
example shown below is a digital caliper as the distances/measurements,
are read from a LCD display. The most important parts have been
labelled. |
|
|
|
The display is turned on with the on/off button. The external jaws should then be brought together until they touch and the zero button should be pressed. The digital caliper can then be used to measure distances. Always go through this procedure when turning on the display for the first time. |
|
MEASURING EXTERNAL DISTANCES |
|
The material to be measured is placed between the external jaws and they are carefully brought together. The locking screw is tightened so that the jaws do not move apart. The digital display can then be read. The distance can be read by in metric and imperial by pressing the inch/mm button. |
|
QUESTIONS: 1. Explain the procedure for preparing to use the digital caliper. 2. Using a digital caliper, measure four external distances |
