Understanding Full Scale Accuracy

Full scale accuracy (FSA) measures the maximum possible error of an instrument relative to its full range or capacity. It is usually expressed as a percentage of the full scale value: Full Scale Accuracy (%)=Maximum ErrorFull Scale Reading×100\text{Full Scale Accuracy (\%)} = \frac{\text{Maximum Error}}{\text{Full Scale Reading}} \times 100Full Scale Accuracy (%)=Full Scale ReadingMaximum Error​×100

Where:

• Maximum Error = difference between measured value and true value
• Full Scale Reading = maximum capacity of the instrument

This helps users understand the tolerance limits and reliability of measuring devices.

Example Calculation

Problem: Determine the full scale accuracy of a pressure gauge with a maximum error of 0.5 units and full scale reading of 100 units.

Solution: Full Scale Accuracy (%)=0.5100×100=0.5%\text{Full Scale Accuracy (\%)} = \frac{0.5}{100} \times 100 = 0.5\%Full Scale Accuracy (%)=1000.5​×100=0.5%

Answer: The instrument has a full scale accuracy of 0.5%, indicating very precise measurements.

Another example:

• Maximum error = 2 units, Full scale = 200 units → FSA = 1%
