Below diagram shows a vernier callipers with a zero error of +0.06 cm.

The least count of the vernier callipers shown in the diagram is 0.01 cm and the 6th division of the vernier scale, coincides with a main scale division.

∴,

Zero Error = 6 × L.C.

Zero Error = 6 × 0.01 cm

⇒ Zero Error=0.06cm

Hence, we get the zero error = 0.06 cm.
