Question

Formula of positive zero error​

Answer 1

Negative zero error refers to the case when the jaws of the vernier caliper are just closed and 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. If positive, the error is subtracted from the mean reading the instrument reads.

0 is not a positive or negative it's always a neutral number
