.
Answers
Answer:
Positive Zero error correction is done by subtracting the positive zero-error from the actual reading.Negative zero error correction is done by adding the negative zero-error from the actual reading
Answer:
Answer:The attached diagram shows cases of zero error in a screw guage.
Answer:The attached diagram shows cases of zero error in a screw guage. Case (a): No zero-error
Answer:The attached diagram shows cases of zero error in a screw guage. Case (a): No zero-errorCase (b): Positive zero-error of 2 circular scale division. Positive zero-error correction is done by subtracting the positive zero-error from the actual reading.
Answer:The attached diagram shows cases of zero error in a screw guage. Case (a): No zero-errorCase (b): Positive zero-error of 2 circular scale division. Positive zero-error correction is done by subtracting the positive zero-error from the actual reading.Case (c): Negative zero-error of 4 circular scale division. Negative zero-error correction is done by adding the negative zero-error from the actual reading.
