# Take a measurement Overview

## Start a measurement

To begin a measurement, press the button on the instrument or the software measurement button, many Aesthetix modules also include an interative measurement feature which allows for accurate sample positioning and live adjustment of measurment parameters.

## Measurement technique
To achieve accurate repeatable measurement, the instrument should remain still during image grabbing stage (red light shown on instrument)).
On large curved parts is always preferable to measure the flattest area where the instrument is stable, alternatively utilise jigs or the measurement stand for small or highly curved parts.
