Please note it is not a requirement to work in "RAW" Units - you can work in an array of different units, please see 'Configuring Units'.

The Analog (varying level) sensors work via a reading taken from the chosen I/O pin in the Entity Tree View>Inputs>Analog Settings driver. The input to these pins typically range from 0-5 volts. This 0-5 volts is then scaled to what is called a RAW value, that is where 0 volts = 0 RAW and 5V = 65,533 RAW.

Tip: If you wanted to work out what the RAW number would be for say 1.3 volts, then it would be 1.3 x (65535 ÷ 5), which equates to approx. 17,000.

The next process that happens, is that these ‘RAW’ readings are converted into a normal units reading, such as degrees, percent or pressure, via the HRT tables, which are shown as the four graphs in the Sensor Cals Screen, or available as indidual tables in the Entity Tree View>HRTs.
