The calibrating gauge for calibrating a Vernier calliper has at least one calibrating face for calibrating a measuring surface for internal measurement, at least one calibrating face for calibrating a measuring surface for external measurement (3) and at least one calibrating face for calibrating a measuring surface for depth measurement (4), the calibrating gauge (1) being in the shape of an at least partly hollow cylinder, on the generated surface (6) of which is provided the calibrating face for calibrating the measuring surface for the external measurement and on the inner surface (10) of which is provided the calibrating face for calibrating the measuring surface for the internal measurement, and the calibrating face for calibrating the measuring surface for the depth measurement being provided on at least one of the end faces (5) of the cylinder.
Calibrating gauge for calibrating a vernier calliper, characterised in that at least one calibrating surface for calibrating a measuring surface for the internal measurement at least one calibrating surface for calibrating a measuring surface for the external measurement and at least one calibrating surface for calibrating a measuring surface for the depth measurement are provided thereon, whereby the calibrating gauge has the form of an at least partially hollow cylinder, on the circumferential surface of which the calibrating surface for calibrating the measuring surface for the external measurement is provided, and on the internal surface of which the calibrating surface for calibrating the measuring surface for the internal measurement is provided, and whereby on at least one of the front sides of the cylinder the calibrating surface for calibrating the measuring surface for the depth measurement is provided.
2 Calibrating gauge according to claim 1, characterised in that the calibrating surface for calibrating the measuring surface for the external measurement is sunk deep into the circumferential surface of the cylinder, so that the diameter of this calibrating surface is smaller than the outside diameter of the cylinder.
Calibrating gauge according to claim 2, characterised in that the height of the calibrating surface for calibrating the measuring surface for the external measurement is adapted in such a way that the calibrating gauge can be used for calibrating a micrometer, in particular in that the height of this calibrating surface amounts to at least 9 mm.
