# How do you calculate full scale accuracy?

## How do you calculate full scale accuracy?

Accuracy as a percentage of full scale is calculated by multiplying the accuracy percentage by the full scale pressure of the gauge. This is obviously a more simple method of specification and is most commonly used in industry because it is easy to calculate and interpret.

## What is full scale in uncertainty?

Full Scale is 30 PSI • Full Scale output is 20 mA • Uncertainty in mA at 30 PSI is 20 mA x 0.5% or ±0.1 mA If you want to do a comparison of two or more different devices, apply the math in the specifications to the same measurement value (for example 20 mA) made with the various instruments.

What is percentage of full scale?

“% of full scale (FS)” accuracy. For example, a 100 psi gauge with 0.1 % of FS accuracy would be accurate to ± 0.1 psi across its entire range. By convention, a gauge specified as 0.1% accuracy is implied to be 0.1% FS.

What is full scale value?

Since binary integer representation range is asymmetrical, full scale is defined using the maximum positive value that can be represented. For example, 16-bit PCM audio is centered on the value 0, and can contain values from −32,768 to +32,767. A signal is at full-scale if it reaches from −32,767 to +32,767.

### What is full scale capacity?

The maximum capacity of a load cell or extension of an extensometer.

### What is full scale range?

“Full scale” indicates the full scope of the measurement range. For example, full scale for a Sensor with a measurement range of ±10 mm is 20 mm.

What is a full scale error?

Full-scale error indicates the offset error (%FSR) between analog input when the maximum conversion value is reached and full-scale (FS) analog input (VREF) in an A/D converter. The full-scale error, zero-scale error, and non-linearity (linear) error constitute the overall error.

Is accuracy a percentage?

In the science of measuring things, “accuracy” refers to the difference between a measurement taken by a measuring tool and an actual value. The relative accuracy of a measurement can be expressed as a percentage; you might say that a thermometer is 98 percent accurate, or that it is accurate within 2 percent.

#### What is the full scale range?

“Full scale” indicates the full scope of the measurement range. For example, full scale for a Sensor with a measurement range of ±10 mm is 20 mm. Error with respect to ideal straight line of linear output.
