The final meter reading is reported to what precision?

The final meter reading is reported to what precision?

• A. 0.25%
• B. 0.5%
• C. 1.0%
• D. 0.1%

Answer: (A)

Reporting the final meter reading to the instrument’s smallest readable increment ensures the result reflects the actual precision of the measurement. If the meter supports 0.25% increments, you round to the nearest 0.25%. That keeps the reported value within the meter’s true measurement capability and avoids implying greater accuracy than the instrument provides. Reporting to 0.1% would be more precise than the device can guarantee, while 0.5% or 1.0% would be coarser than appropriate for this instrument. So the correct precision is 0.25%.
