Vernier Scale - Zero Error

Zero Error

The method to use a vernier scale or caliper with zero error is to use the formula 'actual reading = main scale + vernier scale - (zero error)'. Zero error may arise due to knocks that cause the calibration at the 0.00 mm when the jaws are perfectly closed or just touching each other.

Positive zero error refers to the fact that when the jaws of the vernier caliper are just closed, the reading is a positive reading away from the actual reading of 0.00mm. If the reading is 0.10mm, the zero error is referred to as +0.10mm.

Negative zero error refers to the fact that when the jaws of the vernier caliper are just closed, the reading is a negative reading away from the actual reading of 0.00mm. If the reading is 0.08mm, the zero error is referred to as -0.08mm.

Famous quotes containing the word error:

    In Pride, in reas’ning Pride, our error lies;
    All quit their sphere, and rush into the skies.
    Pride still is aiming at the blest abodes,
    Men would be Angels, Angels would be Gods.
    Alexander Pope (1688–1744)

    Theoretically, I grant you, there is no possibility of error in necessary reasoning. But to speak thus “theoretically,” is to use language in a Pickwickian sense. In practice, and in fact, mathematics is not exempt from that liability to error that affects everything that man does.
    Charles Sanders Peirce (1839–1914)
