These instruments are typically metallic, compasslike, handheld instruments with two adjustable, frequently curved, hinged legs or jaws; some instruments display the results of measurements on analog (e.g., mechanical scales) or digital (electronic) displays. Metallic and/or rigid plastic calipers are available with an L-shaped frame with a linear scale along its longer arm and a second L-shaped sliding arm with an auxiliary graduated scale to facilitate fine adjustment and to increase the accuracy of measurement (i.e., vernier calipers).
