Q: If the ambient temperature is higher than the calibrated temperature of the tape, which of the following errors is it likely to show ?
  • A. The measured distance will be more than the actual distance
  • B. The measured distance will be less than the actual distance
  • C. The measured distance will be equal to the actual distance
  • D. Cannot be determined
Correct Answer: Option B - Correction for temperature:- • If the temperature in the field is more than the temperature at which the tape was standardized, the length of the tape increases, measured distance become less and the correction is therefore additive. Similarly, if the temperature is less, the length of the tape decreases, measured distance becomes more and the correction is Negative.
B. Correction for temperature:- • If the temperature in the field is more than the temperature at which the tape was standardized, the length of the tape increases, measured distance become less and the correction is therefore additive. Similarly, if the temperature is less, the length of the tape decreases, measured distance becomes more and the correction is Negative.
