Zero Error

|||||||||||
It is a defect in a measuring device (Vernier Callipers & Screw Gauge).
When jaws of a Vernier Callipers or Screw Gauge are closed, zero of main scale must coincides with the zero of vernier scale or circular scale in case of screw gauge. If they do not coincide then it is said that a zero error is present in the instrument.
